The Ultimate Guide to Python Programming With Python 3.10 - __main__ module

The video tutorial explains how to import modules in Python and the automatic execution of code that occurs when a module is imported. It discusses the use of if statements to control when certain code should run, specifically focusing on the concept of the main module. The tutorial demonstrates how to use the __name__ attribute to determine if a module is being run directly or imported, allowing for conditional execution of code. This approach helps prevent unnecessary code execution when a module is imported into another module.
