Is there any way to make a python program start an interactive debugger, like what import pdb; pdb.set_trace() instead of actually throwing an exception?

If you are inside the REPL, you can do

import sys
import pdb
pdb.post_mortem(sys.last_traceback)

See https://docs.python.org/2/library/pdb.html and https://docs.python.org/3/library/traceback.html
