I'm with Chris here, I make do with some understanding of Python and a 
generous amount of print statements. My other secret weapon is that I try to 
keep the complexity of my code low ;)

As Python is yet another C program you can of course step through its code 
(debug build) with an appropriate debugger, but I've never done that. My 
guess is that you wouldn't have seen the forest for the trees.
