Setting exit code in Python when an exception is raised


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

I would like to change this exit code from 1 to 3 while still dumping the full stack trace. What's the best way to do this?


Solution

  • 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.
