Python In Practice - 15 Projects to Master Python - User-Defined Errors

The video tutorial covers the concept of exceptions in Python, including predefined and custom exceptions. It demonstrates how to create a Cube class that calculates the cube of a number and handles zero input by raising a custom ZeroCubeError. The tutorial explains the importance of docstrings for documenting code and shows how to use them in functions. It also covers the implementation of try-except blocks to manage errors effectively.
