Large try except block in Python - how to understand where was an exception?

Question

I have a program (not mine) that has a large try - except block. Somewhere in this block there is an exception. what is the best way to find out the exact string of code where it happens?

Answer 1

You can use print_exc in the except block

import traceback
traceback.print_exc()

Example:

import traceback
try:
    pass
    pass
    pass
    pass
    pass
    raise NameError("I dont like your name")
    pass
    pass
    pass
    pass
    pass
except Exception, e:
    traceback.print_exc()

Output

Traceback (most recent call last):
  File "/home/thefourtheye/Desktop/Test.py", line 8, in <module>
    raise NameError("I dont like your name")
NameError: I dont like your name
