Setting exit code in Python when an exception is raised

Question

$ cat e.py
raise Exception
$ python e.py
Traceback (most recent call last):
  File \"e.py\", line 1, in 
    raise Exception
Exception
$ echo $?
1


        

Answer 1

Take a look at the traceback module. You could do the following:

import sys, traceback

try:
  raise Exception()
except:
  traceback.print_exc()
  sys.exit(3)

This will write traceback to standard error and exit with code 3.
