A function is a block of code that performs a specific task. It helps in organizing code into manageable parts and can be called multiple times throughout a program, which makes code reusable. Functions can take inputs (arguments), process them, and return an output. When learning Python language online, understanding functions is essential, as they are a fundamental concept in Python programming. Functions in Python allow you to write clean, efficient code, and they are especially useful when working on larger projects, where reusable code helps reduce redundancy and improves maintainability.
