How Can I Get a Python Module's Path?

Determining a Module's Path in Python

In certain scenarios, it is necessary to access the path of a module to monitor changes or perform specific operations. This article will explore how to retrieve a module's path in Python.

Retrieving the Module's Path

To obtain the path of a module, you can use the __file__ attribute. However, it is important to note that this attribute may point to the compiled .pyc file on some operating systems, such as Mac OS X.

To retrieve the actual path to the original .py source file, you can combine the __file__ attribute with the os.path module:

import a_module
import os
path = os.path.abspath(a_module.__file__)

Alternatively, to obtain the parent directory of the module:

path = os.path.dirname(a_module.__file__)

Example Usage

Consider the following Python script:

# module.py

def main():
    print("Hello from the module!")

if __name__ == "__main__":
    main()

To retrieve the path of this module, you can run:

import module
import os
path = os.path.abspath(module.__file__)
print(path)

This will output the absolute path to the module.py file.
