Hi Jeremy, I am new to Python too. I find docs.python.org very helpful.
*Understanding functions:* http://docs.python.org/tutorial/controlflow.html#defining-functions *Reading and Writing Files:* http://docs.python.org/tutorial/inputoutput.html#reading-and-writing-files *File Objects:* http://docs.python.org/library/stdtypes.html#file-objects *Comments - Coding Style* http://www.python.org/dev/peps/pep-0008/#comments Hope the above links are useful. Thanks, Vignesh On Thu, May 17, 2012 at 11:45 PM, Jeremy Traurig <jeremy.trau...@gmail.com>wrote: > Hello, > > I very new to python and have been playing around with some simple code > that I would eventually use in the real word.
