   Jul 28, 2021 · In any programming language, functions facilitate code reusability. In simple terms, when you want to do something repeatedly, you can define that something as a function and call that function whenever you need to. In this tutorial, we shall learn about user-defined functions in Python.

   How to program solutions in a functional style using Python?

   • Let’s explore how to program solutions in a functional style using Python. In object-oriented programming (OOP), you structure your code based on the concept of objects. In commonly used OOP languages (such as Java or C#), we create a template for an object using the keyword class, and we instantiate an object by using the keyword new.
