Python: Executable Path, Script Path

By Xah Lee. Date: . Last updated: .

Here's how to find various paths from a running script.

Printing path from a running program is important, because if you call it in shell, it may be using a different environment.

Find the Python interpreter path from current script

# -*- coding: utf-8 -*-
# python

import sys

# path of the python program (aka interpreter)
print sys.executable

# sample output on linux
# /usr/bin/python

# sample output on Windows
# C:\Python27\python.exe

Find the path of current running script

get it from the __file__ attribute.

# -*- coding: utf-8 -*-
# python

import os

# path of current script
print os.path.realpath(__file__) # sample output  /home/h3/my-print-path.py

Find a module's path

# -*- coding: utf-8 -*-
# python

import os
print os.__file__     # sample output C:\Python27\lib\os.pyc
