We will cover the following topics on Python Functions: What is a Function? Three possible methods to call a function that returns a value.

Python has a set of built-in functions. Returns a readable version of an object. Replaces none-ascii characters with escape character. Returns a character from the specified Unicode code.

In this blog, we’ll explore the differences between built-in functions and user-defined functions, discuss their respective advantages and use cases, and provide guidance on when to use each, empowering you to make informed decisions in your Python projects.
