What's the best way to retrieve the module path from the project in python?

Question

| foo
|   main.py
|---- one
|    | __init__.py
|------ two
|      | __init__.py

Consider the __init__.py file situated in the foo/one/two/__init__.py. In this file, I want to print the module PATH :

foo/one/two/

What the best way to do that ?

Answer 1

Each module will have a __name__ attribute, which will give you the dot syntax attribute name of the module. e.g.:

from one import two
print two.__name__

This should yield:

one.two

You could then simply replace the dots with the relevant file separater:

import os.path
from one import two
print two.__name__.replace('.', os.path.sep)

This will print (on Linux/Unix etc):

one/two

Or on Windows:

one\two

Answer 2

from foo.one import two
print two.__file__
