7. Functions and Modules

Vaskaran Sarcar¹

This chapter covers user-defined functions, lambda functions, and modules. Using them, you can organize your code in a better way.

Function Overview

You can consider a function as a logical set of statements that perform a specific task. Using them, you can divide your code into manageable pieces, which in turn help you optimize and reuse the code. When you see a function usage in someone’s code, you notice the following things:

They define the function to describe a behavior.
They call the function single or multiple times. ...
