This is the one thing I hate about python, because the spacing would differ between editors. I used vim to create the files on one system, and geany to edit them on another. Via uses 8 spaces in a tab (at least for me), while geany uses 4. This makes python mad, and drives me crazy. 

Also, the rules for whitespace separation between things like loops, methods, and the rest of the code is annoying/ wierd (at least to me).
