Functions in Python

Functions in Python introduce the concept of reusable blocks of code that perform specific tasks, organizing code and reducing repetition. The chapter covers defining and calling functions, using parameters and return values, and differentiating between built-in and user-defined functions. It also explains variable-length arguments and the use of default parameters.
