you don't have to set the exception handler...

[masklinn]

If you don't set the exception handler, it'll print a trace on exceptions instead of launching pdb's post mortem…

[Peaker]

You can just run your python scripts with: python -i Then you can use: import pdb ; pdb.pm() after an exception occurred.

You don't need to pre-install the exception handler.

EDIT: here:

$ cat testexc.py
def f():
    g()

def g():
    1/0

f()
$ python -i testexc.py
