Python 3: Project-based Python, Algorithms, Data Structures - Introduction to branching (if, elif, else) and conditional

The video tutorial introduces functions in Python, starting with built-in functions and moving to custom functions. It explains the structure of a function, including the DEF keyword, naming conventions, and parameters. The tutorial covers return values, both specified and default, and provides examples of functions with and without parameters. It emphasizes the importance of docstrings for documentation and best practices for writing functions. Advanced concepts like multiple return values and upcoming topics such as sorting algorithms and recursive functions are also discussed.
