In terms of debugging, it's hard to ignore the old favorite stand-by:
If In Doubt, Print It Out. Pepper your code with console-output calls
and manually trace your code using those. Every other debugging tool
you'll ever use is a bonus on top of that; if you accustom yourself to
IIDPIO debugging, you'll be able to solve problems in any environment.

Python does have a number of other debugging tools, though. I'd
recommend looking at pylint, for a start. It's not technically a
debugger, but it may be of value.
