If you want to wrap only some inner part of a function, or would need to decorate multiple functions otherwise, a context manager could be used as an alternative to the accepted answer. I am now using this simple version that catches all exceptions. I would also recommend using pudb

@contextmanager
def postmortem_pudb():
    try:
        yield
    except Exception as exc:
        pudb.post_mortem()

Use like this

with postmortem_pudb():
    function_that_might_throw_some()
    ...
    another_function_that_might_throw_some()
    ...
    yet_another_function_that_might_throw_some()
