This is the example code developed during the 
September 10-12 Python class at Schwab (less
typos and long documentation/output listings).

See the file INTERACTIVE-LOG.txt for most of the
code typed live at the Python interactive prompt 
in class.  

Also see file other-INTERACT-LOG.txt for some very
early and very late code that was lost due to IDLE
window closures -- this comes from another class's
log file, but is very similar in all classes.
