python, path of script

I have a Python file, and I would like to parse the path when this file is executed. If I run myPython.py like this:

python ~/Documents/Project/myPython.py

I would like to know the path “~/Documents/Project/” in the file myPython.py.

sys.argv[0] is the path of your script as executed by Python. You can use os.path.dirname() to get just the directory name from that:

import sys, os
print os.dirname(sys.argv[0])

It is OS-dependent if it is the full path entered on the command line; Mac OS X and Linux both include the path.

The path can, however, differ based on how Python invoked it. An alternative is to use __file__, and you can make the path absolute by using os.path.abspath() and os.path.expanduser() to cover all variations:

print os.path.dirname(os.path.abspath(os.path.expanduser(__file__)))
