How to recover from exception when debugging python?

Question

When stepping through the code in pdb, any exception hit immediately ends the program. How do I instead fix the exception and keep debugging? Is there no way to avoid the overhead of restarting the program?

It seems like many py debuggers share this annoyance: pdb, ipdb, pycharm, pydev.

You could catch the exception, run `pdb.post_mortem()` in the `except` block to poke around a bit, and then execution will continue since the exception has been handled. — wbadart, Jul 31 '17 at 18:54

Once I find where it's crashing, I'll often set up try/except blocks to help figure out why.

try:
    # code that causes exception
except WhateverException as err:  # be specific with the type of exception  
    import pdb; pdb.set_trace()
else:
    # do what you'd normally do
