What are Python modules used for?

They split code into reusable .py files with functions, classes, vars — perfect for organization and sharing.

How do I import a Python module from another folder?

Add the folder to sys.path or use relative imports in packages with __init__.py.

Avoid it — risks name clashes. Stick to explicit imports.

Python modules aren't just files—they're the glue holding massive projects together. Skip them, and your code turns into spaghetti.
