How to Efficiently Import Modules from a Python Folder?

Importing Modules from a Folder

When organizing your Python code, it often becomes necessary to import multiple modules from a specific folder. One common approach involves converting the folder into a Python package by adding an __init__.py file at the root.

The __init__.py Approach

By creating an __init__.py file, you can import the modules within the folder as follows:

from my_package import *

However, this approach may not always be ideal, as it imports all modules from the folder, irrespective of whether you need them or not.

Importing Specific Modules Dynamically

To selectively import modules from a folder, you can utilize the following code:

import os
import inspect

# Get the current folder path
folder_path = os.path.dirname(os.path.abspath(inspect.getfile(inspect.currentframe())))

# Iterate over all .py files in the folder
for file_name in os.listdir(folder_path):
    if file_name.endswith('.py') and file_name != '__init__.py':
        # Import the module using dynamic import
        module_name = file_name[:-3]
        module = __import__(module_name, fromlist=['*'])

Using this method, you can import specific modules within the folder by accessing them via the module_name variable.
