[Tutor] way to see code execution in real-time?

Hey everybody,

Thanks for the recommendations -- I usually do use pdb to step through
chunks of code, but always by setting a breakpoint. And then I have to
"manually" print out the variables to see what's going on in the code.

Is there a way to wrestle pdb into spitting out the code being
executed, as it executes (without having to manually do so myself)?

Perhaps a profiler will get me most of the way to where. The time
element isn't as necessary for me as understanding what gets fired,
how many times, etc. It would be great to see the order of execution,
so I'll try CodeInvestigator to see if that will do the trick.

Meantime, thanks as always!

Serdar
