Python 3 for Beginners: Python Standard Library and Creating Modules in Python

The video tutorial introduces Python's standard library, emphasizing the use of existing modules like CSV, logging, and HTTP requests to avoid reinventing the wheel. It explains how to handle errors using the SYS module's exit method. The tutorial also covers creating custom modules and importing them into other programs. It highlights the importance of controlling module execution behavior using the __name__ variable, allowing different behaviors when a module is run directly or imported. This approach is common in Python applications, ensuring that code is only executed when intended.
