Python 3 for Beginners: Python Modules

The video tutorial covers the basics of Python modules, including their creation, importation, and the default search path. It explains how to modify the module search path and introduces the Python Standard Library for code reuse. The tutorial also demonstrates using the DIR function to explore module contents and guides on creating personal libraries by writing custom modules. Finally, it discusses controlling program behavior based on whether it is run interactively or imported, using the special variable __name__.
