[Tutor] Need a Clean Start

[Keegan Johnson]

Hi everyone,
I'm taking a computer science class. We haven't gotten to Python yet  
but I've started dabbling and become rather enamored. Anyway, I've  
been using different versions and have installed different things and  
am going crazy. I need to get the pygames, py2app, etc on my computer  
(I have a Macintosh). Is there any way to clean up all these files  
that I've accrued trying to get things to work? I've been able to do  
a little bit but nothing more than that. Also, what should I use?  
There's lots of different versions different sites recommend. Anyone  
willing to authoritatively decide?
Thanks a million for any help at all,
Keegan
