Find path to currently running file

Question

How can I find the full path to the currently running Python script? That is to say, what do I have to do to achieve this:

$ pwd
/tmp
$ python baz.py
running         


        

Answer 1

The script name will (always?) be the first index of sys.argv:

import sys
print sys.argv[0]

An even easier way to find the path of your running script:

os.path.dirname(sys.argv[0])
