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

Python 3.7 adds that feature

From the docs, it looks that your command:

python -m pdb -m my_module

will start working on Python 3.7:

New in version 3.7: pdb.py now accepts a -m option that execute modules similar to the way python3 -m does. As with a script, the debugger will pause execution just before the first line of the module.
