How to debug a Python module run with python -m from the command line?

Question

I know that a Python script can be debugged from the command line with

python -m pdb my_script.py

if my_script.py is a script

Answer 1

According to the python command-line manpage the -m flag does the following:

Searches sys.path for the named module and runs the corresponding .py file as a script.

Given this, I would feel confident debugging by running the .py file as per your first example. One thing to keep in mind is that -m searches sys.path. Luckily, python looks at the current working directory first, so as long as the .py you are debugging is in your cwd, python -m module and python module.py equivalent.
