[CentralOH] Breaking Out Of Nested Loops

[Travis Risner]

Hi Jim,

T Python Pocket Reference book describes the function of the break 
statement and goes on to say "...Hint, raise and try statements can be 
used to exit multiple loop levels." nothing more.

I wrote a program to test it out.  It is available at

https://github.com/deeppunster/deep-punster/blob/master/play_break.py

HTH,
Travis
