What is Function in Python

Definition

A function in Python is a reusable block of code that performs a specific task. Functions can accept input arguments, process them, and return a result.

Advantages

• Write code once and reuse it multiple times
• Improves code readability by organizing code into logical blocks.
• Easier to maintain and update code

Uses
