Packages are nothing more than folders that contain an __init__.py file.

What might happen if we forget to add such a file?

Python won't recognize the folder as a packageWe can still import functionsWe can still import packages but not subpackages

Perfect! Without the __init__.py file, which can be empty, Python won't know that the folder is a package.

Might it be that, without the __init__.py file, Python has no way to know that a folder is a package?
