Python 3 Modules vs. filenames

Question

What is the difference and relationship between module names and filenames in Python 3? Must a module name always be identical to the filename?

Answer 1

A module\module_name can be one of these:

• file
• folder
• folder with __init__.py inside of it
• __main__ module name (the file you just run...)
• you can change your module name or insert an object to *sys.modules that will appear as a module
