Python: Find Script Path

Here's how to find python executable path, current script path, module path, 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

Python interpreter path is stored in:

sys.executable

import sys

print(sys.version)
# 3.9.1 (tags/v3.9.1:1e5d33e, Dec  7 2020, 17:08:21) [MSC v.1927 64 bit (AMD64)]

# path of the python interpreter
print(sys.executable)
# C:\Python39\python.exe

Find the path of current running script

Path of current running script is stored in the attribute:

__file__

import os

# path of current script
print(os.path.realpath(__file__))

# /Users/xah/web/xahlee_info/python/xxtemp.20190319.288.py3

Find a module's path

Module's path is stored at variable

moduleName.__file__

import os
print(os.__file__)

# /Users/xah/anaconda3/lib/python3.7/os.py
