Python User Defined Functions for Beginners: Passing Parameters, Arguments & Return Values Explained

In this video of the Python for Beginners tutorial, we dive deep into the essentials of user-defined functions. Learn the difference between built-in and user-defined functions, how to create your own user-defined functions with and without parameters, and understand the role of the "return" statement and "docstrings". We’ll also explore how to effectively use parameters in your code, the difference between parameters and arguments, and how to pass default arguments, arbitrary arguments, and collections, including list, tuple, set and dictionary, to user-defined functions. All hands-on examples will be demonstrated in IDLE.
