Python Activities History (So Far)

This page chronicles my Python training and writing careers. It itemizes the Python classes I taught, my Python books released along the way, and articles and interviews I did over the years, with totals for each category in parenthesis. For both context and color, I've also liberally peppered this page with anecdotes, observations, photos, and jokes (a.k.a. memoirs, but not the stuffy kind). Because my training and writing careers played a major role in Python's adoption, readers are invited to consider this page part of Python's history too.

Two notes up front. First, this sort of page is unavoidably first-person, so please click away now if you're not interested in writing that's laden with "I" and "my." Some might even deem this page spectacularly self-promotional (if not egregiously egocentric), but such is the nature of career retrospectives, and you might find parts of it interesting anyhow. Second, the items below go as far back as 1993, and are listed with the most recent year first; read from the end if you prefer to move forward in time (on this page, at least).

The Numbers

All told, I've been using and promoting Python since 1992 and version 0.9. On the training front, the 260 live and in-person classes I taught from 1997 through 2015 included 5 in the UK and Ireland; 3 in Spain; 2 or 3 each in Puerto Rico, Canada, and Mexico; 3 in NYC; 8 in Texas; 13 each in the DC and Boston areas; 17 in Chicago; and 52 in California. In the writing department, since 1996 I've published 14 books—3 titles in 4 or 5 editions each—which spanned 11,000 total pages, covered Pythons 1.X through 3.X, and sold over 550,000 book units as of mid-2016 sales data.

Technically, 10 of the 35 years I've spent in the software field preceded my stumbling onto Python, and included two degrees in computer science, work in the compilers and Prolog realms, and a first substantial program in 1982 using Fortran on punch cards (it played tic-tac-toe against itself, and somehow always won). But such prehistory is officially outside the scope of this page.

More relevant here: today Python is generally counted as one of the top 5 most-used programming languages in the world; there are hundreds of Python books available on Amazon; and the local Barnes & Noble has an entire labeled section dedicated to the language. Among the best rewards of my career is the knowledge that my Python activities—whose beginnings predate the rise of Python, both Google and Amazon, and most of today's online experience—had something to do with that.

The Years

If you prefer clicking over scrolling, here's a table of the year sections in this page:

Public classes were open to individual enrollments, and most were held locally. Private classes (sometimes called on-site classes) were arranged for clients with groups, and were held both locally and out-of-town. All my classes were private sessions as of October 2010; I no longer scheduled public classes after that date for reasons you'll read about ahead.

Host Names

Please note that the hosting organization names listed here do not constitute endorsements of any kind for either Python or my training services. These names, where still known and not recent commercial entities, are included here for their historical value only. It is assumed that the passage of time makes naming hosts a moot point, but please contact me if your organization prefers anonymity for these classes.

Current Status

Also note the "(So Far)" in this page's title; to quote from Python's namesake: I'm not dead yet... While this page was accurate as of its latest update on September 18, 2016, it is neither rigorously nor regularly maintained, and may not document activities in later years. Please contact me for current status, and watch this page for book news.

 2016

This year saw both book milestones, and the expected and arguably-overdue conclusion to the training story. On the former, Programming Python turned 20 years old this year, and sales of the Learning Python title reached the 300k units mark (not counting all the free copies downloaded illegally on the web).

Happy Birthday, PP

Programming Python was first published in 1996, though its development (and lobbying) began a year or two earlier. Its content has spanned Pythons 1.X through 3.X, and was the genesis of my other two books—Learning Python and Python Pocket Reference. Together, these three related books' sales reached 550k units by April this year, and will continue to grow in years ahead. For a look back at this book's history, see the earlier years on this page, especially its birth in 1996. Over the years, it grew into a mature applications text; maybe now it will finally move out of my basement...

The Plumage Don't Enter Into It

After 20 years, 260 live and in-person classes, and more adventures than I can recall, I finally ended my Python training business in full this year. See the formal announcement for details. You can also read about some of the factors behind this decision in 2012 and 2010 below.

In short, it's high time to accept that onsite Python classes taught by subject matter experts for forward-looking groups have gone the way of the Norwegian Blue. This probably says something about society at large, and almost certainly reflects Python's rise to ubiquity, but I'll pass on elaborating here. Instead, I'll close out the training thread on this page with thanks to all my clients for an amazing two decades, and hopes that the books which mirror my former classes prove as useful to learners of the future as they have to learners of the past.

As for training, though, it has ceased to be. For posterity's sake, I've posted a few photos from the training road, and the final version of the class workbook material. On my watch, the latter morphed from paper copies and floppy disks, to HTML, CDs, USB flashdrives, and the web. I don't know what comes next, but I'm sure we'll think of something. For now—roll the closing credits!

May-2016 Interview, pythonlibrary.org PyDev of the Week

 2015

On-site classes were resumed this year after the book projects, but at a much-reduced pace.

Python by the Pound

On the training front, the NASA class was for structural engineers, and the UW group was network administrators; Python's roles are still very diverse. On the writing front, my books' combined lifetime sales surpassed the 500k units mark this year, and are on track to reach 600k units in the next year or two. By my calculations, the paper units sold so far weigh in at over 650 tons (please don't tell the firs behind my house).

With Publishers Like These...

Despite capping a three-year sales peak, this year also saw some uncertainty over future editions. My publisher passed on updating a classic Python book over a trivial contract issue, and demoted both open source and books in general at their web site. Once known for meaty technical books, this publisher seems to be morphing into a company focused on videos, webcasts, and conferences; with a business model based on pandering to a naive audience instead of educating it; and a web presence that has become a platform for promoting illegitimate content and personalities. This is not the publisher I signed up with.

Time will tell if legacies that established this company's brand are compatible with chasing the latest trends. Time will also tell if this publisher remains a net positive for my books. As it stands, though, its current image seems just as likely to turn away legitimate readers as it is to attract them. Looking for solid technical material at this publisher's web site today is like looking for Principia Mathematica in People Magazine. Follow this developing story here.

For more drama on the books front, see also the May-2016 note here. In short, my publisher started selling and even preferentially promoting another publisher's "Learning Python" late this year, in a curious and arguably misguided quest to maximize revenue, which undoubtedly left many readers confused. Competition is great, except when it comes from your own publisher.

Update: September, 2016 saw this strange and sad scene on Amazon.com—sponsored content from my publisher, that showed up above my book in searches for "Learning Python," and was designed to lure buyers away to video options. Whether marketing blunder or darker agenda, this company is now actively working against its own best-selling products (and its own half-million unit author). Be careful with your publishing choices out there, people.

(Ongoing) Article, this site Python Changes 2014+

 2014 and 2013

These years were focused on two major book projects. A one-person training business is a massive undertaking, especially when travel is involved, and the book updates merited the complete and fulltime attention they finally received.

Book:1, Keyboard:0

The 5th edition of Learning Python released in this period becomes the best-selling edition so far, on track to hit 100k units by itself, and push the title's lifetime sales well past the 300k units mark by mid-2016. It also concludes with a warning about feature bloat and language flux in Python—a trend which continues unabated to this day (more on recent Python changes at this page).

With these years' publications, the total page count on the 14 Python books I've published over the last two decades reached 11,000. To put that number in perspective, 11,000 pages is equivalent to 22 500-page books, 31 350-page books, or 44 250-page books. To put the work in perspective, the latest Learning Python project was so intense that it killed a keyboard on a brand new Ultrabook. Yet another gadget that bravely gave its life to keep the world safe from bad programming language design (more on device tragedies in 2006 and 2005).

Oct-2014 Interview, Dice.com Interview Qs for Python Newcomers
Jul-2013 Article, O'Reilly Radar Python’s New-Style Inheritance Algorithm

 2012

Unavailable for training the first part of this year (due to another cross-country relocation), and writing fulltime as of October (which eventually became a two year training break).

Idiocracy Cometh?

Somewhere along the way, the recession impacts training budgets; Python sheds its newness and becomes an expected-to-know skill in jobs, and an expected-to-learn subject in universities; and the world loses its mind and decides that complex technical skills like software development can be easily learned by watching a few hours of YouTube videos, copying code from unqualified Github sources, and following arbitrarily misinformed Stack Overflow advice.

While all three trends seem to have taken a toll on the in-person Python training field, the latter threatens a more disastrous impact on the software world at large. People may eventually realize that videos and webcasts are not training, cut-and-paste is not programming, and the knowledge of peers does not have the same innate value as that of subject matter experts. But this may take time (and widespread software failure, unfortunately).

For my take on virtual training, see this note. For more on the cultural changes it reflects, see the "democratization" of knowledge—a broader and strangely naive trend rooted in denigration of experts, which, if applied literally, seems destined to yield either economic decline or outright anarchy. In the software field, this trend's fruit sacrifices quality of craft in the name of a modern gold rush which is more marketing hyperbole than hiring reality. Knowledge requirements in engineering domains cannot be crowdsourced, despite what you may have heard.

Broader issues aside, a live in-person class is a tough sell to a crowd that has convinced itself (or been convinced) that any skill can be had with a quick tour online, and for proof can point to a multitude of high-level and largely useless overviews available for free on the web. Trust me on this; nothing captures the impact of the Internet quite as well as watching students search for answers by wading through online resources, instead of asking the real expert standing three feet behind them.

On the other hand, my books' sales in this same period are stronger than they have ever been, and will increase further in the years ahead. Perhaps there is hope for the Rebellion still.

On-site training resurges. I stopped training as of August this year to avoid being too busy; this wound up being a full year break.

Brownshirts ♥ Belts

Memories from the road this year—a snow day in Boxboro, subzero cold in Chicago, a tornado warning in Bloomington, homeless people in San Francisco, and a lost belt courtesy of an antagonistic TSA agent in Boston's Logan airport. Business travel is losing its luster.

 2010

This year saw the end of public classes; the last three were held in Sarasota. In short, more and more public class students were showing up with highly over-inflated expectations, and it became unethical to take money from individuals in this context.

Expectations and Exploitations

By this time, Python's original message of a better tool for developers had become a promise of accessibility to everyone. This was reflected in an increasing number of public class students with no background in programming, expecting to launch a software career after a 3-day class. Disreputable marketing in the publishing and training fields was no doubt a big factor behind this shift, but a general cultural change was also at work which denigrated both the software field and traditional learning (more on this in 2012). Whatever the cause, profiting from the desperation of misled people is just plain wrong.

In contrast, private classes and comprehensive books are targeted at very different audiences—the former at groups with specific job-skill requirements, and the latter at individuals seeking in-depth coverage. Still, the tech education field is sorely in need of realism. Software engineering is not, and never will be, a trivial skill to master; promising otherwise is at best naive, and at worst fraud. Either way, the net result is to both disappoint newcomers and dilute the field.

 2009

Most of this year was still local classes only (and referring contacts to others), but the London class in December signaled a restart of travel-based classes which continued into later years. Book update projects were also underway much of the year—necessitated by the need to cover the newly-released Python 3.X. Much of the work on books this year was done during a cross-country move, and some of it on a cramped netbook.

The Python 3.X Paradox

The Programming Python update is pushed out to next year. It will be held in limbo for months by the publisher, and have to grapple with half-finished 3.X libraries that are still being brought in line with 3.X language changes, and are sufficiently incompatible to make 3.X conversion a lot more complicated than running code through a syntax converter. In the end, many standard libraries won't correctly handle 3.X's Unicode model until years after 3.X's release—further slowing its adoption. Moral lesson: if you're going to mandate change, you should at least have the common sense to practice what you preach.

On the upside, Python 3.X will eventually become fully usable for applications work, if programmers are careful to stick with its large subset that applies to all 3.X versions (see the frigcal program for a prime example). Unfortunately, the siren call of latest-and-greatest inevitably lures many a coder to the rocks of incompatibility. There's more on the Python changes story here.

This year was local classes only, a continuation of 2007's mid-year change, and a policy that also lasted for most of the next year. Even so, a single longstanding client sufficed to fill some of the time—and give my second OQO a workout when a laptop failed to project.

The Python 3.0 Preemie

The deliberately backward-incompatible Python 3.0 is released late this year—by most accounts an atrocious misstep, which is no longer mentioned in 3.X circles. The Python 3.X line will eventually become more robust and efficient, but remain a constantly morphing sandbox of ideas which will struggle to attract users, and will even alienate some former Python fans. By contrast, the Python 2.X line will soon be frozen at version 2.7; despite 3.X's emergence, 2.X will continue to see widespread use (and probably always will).

mid-2008 Interview, Quantum Books Learning Python topics

 2007

This year was a turning point for training: for happy personal reasons, I stopped doing out-of-town classes at mid-year, and did only local classes (public and private) from then until December 2009—a business travel break spanning two and a half years. This was still a high-demand year and I passed along a lot of business to others, but personal lives sometimes trump careers.

How (Not) to Annoy Readers

This year also saw the release of the 3rd edition of Learning Python: a heavy revision that incorporated new training experiences, and dropped the material of the prior edition's coauthor (who elected not to work on the update). The new edition was also temporary host to both arguably-annoying "Brain Builder" section labels and definitely-distracting code section pointers added by the publisher over my objections. It enjoyed strong sales until Python 3.0 forced an update ahead of schedule.

Nov-2017 Interview, Dr. Dobb's Learning Python Today and Tomorrow

 2006

The peak year for training, though 2007 would have probably been similar if I hadn't taken a break from travel. I likely spent more time in hotels this year than at home. In fact, the pace was so busy that I had to pencil myself in as unavailable for classes in September to get a break (and meet someone who would change my life profoundly next year). A large book was also somehow written this year; much of the work was late-night hotel vigils.

The Google Joke

Among training notables: classes amongst the Chicago skyscrapers; a New York class near the now heavily-armed Wall Street; lost luggage in Edmonton which made for an interesting wardrobe; an OQO Windows-based handheld computer doused badly in London by an errant pint of Guinness; and a class on the Google campus. The Google class almost didn't happen, because I refused to allow background checks that were more invasive than those of the NSA. (That's how I know they're different.)

Sep-2006 Interview, Tech Talk Radio Discussion thread

 2005

The second-biggest year for training. Tech, Python, and programming in general were surging. This is also the last year that I attended conferences; after doing 12, they grew repetitive and stale for me, unwanted attention was becoming a burden, and I already had a heavy-duty travel schedule for training.

Da Da Dang Dang Dang

This year also saw a return to Puerto Rico (and the best shrimp on the planet); a disabled laptop (thanks to an unfortunate Diet Coke incident in Berkeley); and a hands-on look at a NASA virtual reality cave (before VR was cool). A second hurricane off the coast near St Augustine added color to the Palatka class, and a Colorado blizzard delayed arrival to West Palm Beach.

The Big Nerd Ranch public classes in this year and the next were held at a retreat in the Georgia woods, where students and instructor would stay and eat, and share a week-long learning experience while largely cut off from the outside world. Yes; cue the banjo.

The dot-com effect ebbs, and a recovery seems to be afoot. Conferences were already starting to get old for me by this point; I stepped out of the DC PyCon to watch a US presidential campaign rally down the street.

I'll try "Spam" for $100

This year's training included a beach stay in Florida, a 1-person class in Fresno, the remnants of a hurricane in Newport News, and an NSA class which banned student CDs I brought along (training takes on a different tone when the client has automatic weapons). I was also asked to provide a final exam for students at Circuit City's HQ; so I wrote up an easy exam filled with jokes; which most of the students failed...

Feb-2004 Article, ONLamp.com When Pythons Attack

 2003

This was a low-point for training, and seems to be the year when the full impact of the dot-com crash's downturn hit. I cancelled only one public class due to low demand, and it was in March of this year. My publisher nearly folded in this timeframe as well. That would never happen to this field again, right?

Of Mice and Movies

Despite the decline, this year had its share of memorable training moments, including a return to Dublin, the Big Dig in Boston, and tours of both a control room at Disney World and a movie studio lot in Culver City. In the books department, Learning Python, 2nd Edition is released with new material from recent classes and Python changes; this wound up being a one-person job, but retained the prior edition's coauthor material.

 2002

An early high-point for training, and an apparent vindication of the career move. The dot-com burst had happened, but it hadn't hit training demand yet (see next year).

¿Dónde está la clase?

This year's trips to Barcelona and Mexico City were rewards in themselves. The former included an entire weekend to explore, with a day spent on Las Ramblas and the Mediterranean (photos here and here). The latter saw squash games, amazing food, and a tense moment when a police officer jumped into my taxi as a random kidnapping deterrent. Spoiler alert: I'll return to UW in Seattle 13 years later, when nobody will recall the class held there this year.

 2001

Growing training demand, and the first of many book updates to come.

Shaken (But Not Stirred)

Among this year's training highlights: actor Richard Kiel ("Jaws" in James Bond movies) popped in at the class in Oakhurst near Yosemite; I was stranded in Seattle by an earthquake following the Vancouver class; and the Dublin class was more fun than work (think millennia of history and fresh Guinness on Grafton Street). Dublin was also part of a six-leg trip that included a cross-country drive, a conference tutorial in San Diego, and a side trip to visit relatives in Arizona; travel was now a constant.

What's In a Name?

Early public classes in this year and 2000 were hosted by a Perl training company based in Boulder, Colorado (TCPC); I eventually started holding these in Colorado myself this year. Also this year: both an OSCON (held by my publisher) and an IPC (held by Pythonfolk), though conference details this far back start to become a bit murky, due to thinning Web records (and memory); t-shirts seem the best definitive proof remaining for some. Older conferences may still be spotted here, here, and here.

This year's 2nd edition of Programming Python was a very different book than its predecessor. Given the presence of Learning Python's language tutorial and the Python Pocket Reference's quick-reference, the new Programming Python edition is able to morph from a general and broad text to a focused and more advanced applications tutorial. This scope remains with the book in all its later editions. It probably should have been rebranded as "Applying Python" or some such at this point, but the publisher had already established the title model.

May-2001 Interview, ONLamp.com Programming Python topics

 2000

The first fulltime training year, and demand was high enough to justify the risk.

Two Managers Walk Into a Bar...

The UK trip to Newmarket near Cambridge this year was the first overseas class (photos here and here). It would be followed by later international classes in Mexico, Canada, and Europe, with 7 training trips to the latter. Poignant memory: the New York class was held across from the World Trade Center. Geek memory: the Chicago class was for the maker of the Palm, a line of PDAs I used almost constantly until the Linux-based Zaurus justified migration (see 2006 for my later defection to Windows).

I also recall teaching a one-day Python overview in New Jersey this year which included the usual good-natured jokes about managers, only to be told later that the entire audience consisted of managers evaluating the language. Hence the silence.

Python 2.X Arrives

Python 2.0 is released this year, with full backward compatibility and minor extensions; by 2008, 3.0 will differ widely on both counts. Some of the changes that will eventually be mandated in 3.X, such as new-style classes, will premier along the way as options in the 2.X line, adding to the confusion of users trying to discern between the two. Nevertheless, the 2.X line will go on to preside over Python's primary ascendance; enjoy a de-facto standard with its freeze at version 2.7; and remain a popular production-grade tool long after 3.X appears.

 1999

Mostly teaching classes on vacation time while working as a C++ consultant. I finally quit my "day job" in October to take a completely unjustified chance on doing training and writing fulltime; and never went back.

A Series is Born

The first Learning Python is released this year—a title that my late first editor wanted as a simpler introduction for "everyone else," and which wound up being the best seller of the bunch. This book's genesis was the tutorial appendix in the first Programming Python, which will now be free to narrow its scope. From here on, Learning covers language fundamentals that span all domains, and Programming shows what you can do with the language after you've learned it. Here's O'Reilly's original page for the new book way back in 1999; shopping carts are by now all the rage.

 1998

A few classes for forward-looking organizations and assorted writing projects, while still working fulltime as a software developer (yes, people multitasked before smartphones). Training was still a very minor sidelight activity at this point, though Puerto Rico was an undisputed highlight of the year.

Pocket Change

For the Handbook below, I contributed a 120-page chapter, which was mostly an abbreviated version of Programming Python material (considerable work, but it doesn't quite count as a book in my book). The first Python Pocket Reference published this year was an expanded version of an appendix in the first Programming Python; by its 5th edition in 2014, it would become a more complete 260-page reference book (and require a substantially-larger pocket).

 1997

The first year of formal training—an activity I never planned to do, but which wound up fully consuming my career. People in San Jose and Livermore called to ask if I'd do a class, and I took some vacation time to accommodate them. Books probably led to the training, but in the end, the two activities wound up providing crucial input to each other. There's really no better way to hone a book's presentation than by running it past multiple critical audiences.

Early Gigs and Gaffes

From this point forward, training was an unexpected, "make it up as you go along" activity. The first class in San Jose required rebooting a room full of SGI workstations due to an infinite loop bug in Python 1.5's print, and the second in Livermore was delayed by a snowstorm in Colorado. Not exactly a stellar kickoff, but onsite training requires extreme flexibility. Early classes included paper copies of the class workbook, used overhead-projector transparencies, and provided student materials on floppy disk; that's how long ago this was.

Jan-1997 Interview, CompuServe Programming Python topics

 1996 and Earlier

The first Programming Python is published: a book which arguably established Python's legitimacy, and eventually spawned both Learning Python and Python Pocket Reference—a 3-title set that would go on to sell 550k units as of mid-2016 (not counting Safari readers, some underreported translation sales, and illegal copies fetched off the web). In 1996, I thought we'd be lucky to sell 5,000 books. Courtesy of the Wayback Machine: O'Reilly's original page for this book in 1996; neither Amazon nor online ordering was quite there yet (and Google was busy coding their first web crawler in Python).

A Book is Born

My publisher initially rejected the book idea (they were focused on Perl at the time, and Python was just one of a set of obscure tools) but relented after months of lobbying on my part. The fruits of that stubbornness seem clear: today, Python is a large and profitable domain for most technical publishers, and is generally counted among the most widely-used programming languages in the world. I also gave previews of the book at two early Python conferences listed below, the second of which spawned what proved to be incredibly shortsighted remarks about a book being unnecessary. Such is life in the ego-based world of open source.

This book's conclusion argued for Python's role in simplifying the work of professional developers, and was retained by all its editions. Two decades later, that argument still holds true: Python remains an enabling technology in the hands of skilled programmers. As discussed in 2010, though, this original premise seems to have been perverted over the years into a promise of instant accessibility for all. That was never the point. Python can be loads of fun, and I'm glad my books inspire newcomers, but mastery in this field takes more time and focus than commonly told. I hope this page has underscored the importance of honesty on that front.

It's also worth noting that Programming Python was indeed the first Python book started, but not the first sold: another book beat this book to market by a few months—and was rushed out specifically to do so, with a primary author who had just served as a technical reviewer for Programming Python. In the end, the other book's content overlap was minor, but it also never had commercial success and soon went out of print. By contrast, Programming Python has had a 20-year shelf life. And counting.

Etcetera

And before all this, there were monsters that roamed the earth, of course, and answered to names such as Perl, Tcl, and C++, but that story is beyond this page's scope. For more on my Python work, see my formal bio; this page's photos (plus a few more); the relics and articles listed here; the index pages for my three book titles here, here, and here; and the 1993 post from the halcyon days of Python 0.X that got me into all this trouble.
