It’s pretty simple to have your python script jump out to the debugger.  Place these 2 lines right before where you want to start monitoring (otherwise, you’ll need to do a lot of stepping thru code).

import pdb
pdb.set_trace()

Some useful ones to remember are:

• b: set a breakpoint
• c: continue debugging until you hit a breakpoint
• s: step through the code
• n: to go to next line of code
• l: list source code for the current file (default: 11 lines including the line being executed)
• u: navigate up a stack frame
• d: navigate down a stack frame
• p: to print the value of an expression in the current context
