How Can I Dynamically Import All Modules from a Directory in Python?

Loading Modules Dynamically from a Directory

Question:

Importing modules from a specific directory can be challenging. Consider the following directory structure:

/Foo
    bar.py
    spam.py
    eggs.py

Importing the modules using __init__.py and from Foo import * does not yield the desired result. How can one import all modules from this directory dynamically?

Answer:

Create an init__.py File with __all Variable

1. Within __init__.py in the Foo directory, list all Python (.py) files in the current folder.
2. Use Python's __all__ variable to specify the modules to be imported.

from os.path import dirname, basename, isfile, join
import glob
modules = glob.glob(join(dirname(__file__), "*.py"))
__all__ = [ basename(f)[:-3] for f in modules if isfile(f) and not f.endswith('__init__.py')]

Example Usage:

After creating the __init__.py file, you can now import all modules from the Foo directory using:

from Foo import *

This will dynamically import all available modules within the Foo directory.
