What is the purpose of a function in Python?

The purpose of a function in Python is to organize and reuse code.
Functions in Python encapsulate a set of instructions that perform a specific task. They allow you to break down your program into smaller, manageable pieces, making the code more organized, readable, and maintainable. By defining functions, you can avoid redundancy by reusing the same block of code multiple times throughout your program. This promotes code reusability and modularity, which are essential principles in software development. While Python supports arithmetic operations, graphical interfaces, and class definitions, these are not the primary purpose of functions.
