How do I get the file path of python script within loaded module?

Question

I wrote a module module.py that I import in various scripts. The module has a function that needs the file path of the script main.py that it was imported by and do something with it. How do I get this file path?

module.py

def main_file_path():
    print(way_to_acces_main_file_path)

is imported in

main.py

import module
module.main_file_path()

Running main.py should print the file path of main.py

Why not just pass in a path into main_file_path? This will also make it more reusable and generalized. — DeepSpace

Because the real function in module.py always needs the file path of the script that imports it, and this function already has a few parameters. I think adding the file path as parameter will complicate the function. I am looking for something like file that I can call in the module. — Timo

This is an odd request. Are you sure there isn't a better way to do what you are trying to do? — Keith

The system argv always has the program name as the first element. This should work most of the time:

import sys
import os

path = os.path.abspath(sys.argv[0])
print(path)

This works perfectly for what I intended. I wasn't aware that sys.argv[0] also gives the script name that is being executed when called inside a module. Thanks!

You can use the os module to get the path of a file:

# file_locator.py

import os


def get_file_location(filename):
    return os.path.abspath(filename)


if __name__ == '__main__':
    pass

# main.py

from file_locator import get_file_location

fileA = get_file_location(filename)

This would work if I only import module.py in main.py, but I use it in other scripts and want it to be flexible in regards to which script it is imported by.

I updated the code. Does this offer the flexibility you are trying to achieve?
