Is object-oriented programming paradigm mandatory when using Python?

The object-oriented programming (OOP) paradigm is not mandatory when using Python. Python is a multi-paradigm language that supports procedural, functional, and object-oriented programming.

You can write scripts and programs without using classes and objects, by using functions and modules. However, OOP is often used to organize code, especially in large projects, due to concepts such as encapsulation, inheritance, and polymorphism.
