Adding a --pdb flag to your applications can make them much easier for
those using it to debug your application, especially if your applicatoin
is a cli application where the user has much fewer options to start this
for themselves. To add a pdb flag --pdb to your applications you will
need to wrap your function call in a try/except, and start a post_mortem
debugger. I give credit to
this stack overflow post
for helping me figure this out.
import pdb, traceback, sys
def bombs():
a = []
print(a[0])
if name == "main":
if "--pdb" in sys.argv:
try:
bombs()
except:
extype, value, tb = sys.exc_info()
traceback.print_exc()
pdb.post_mortem(tb)
else:
bombs()
Using --pdb
python yourfile.py --pdb
