[Baypiggies] call for newbie nuggets

[jim]

   step right up, present your newbie nugget, spot open 
for our december meeting (monday 20091214) and all of 
2010. 
   a newbie nugget is a short (five to ten minute or so) 
explanation of some python coding technique or feature 
that is "pythonic" and likely not to be familiar to 
those who've used other programming languages and are 
new to python. topics might include commenting conventions, 
doc testing, atomic data types, libraries (e.g. arrays, 
typically available in other languages, but not in the 
python language), intro to unit testing....
