On the other hand, a def (function definition) is a block of reusable code that performs a specific task. While functions are standalone blocks of code, classes define the structure and behavior of objects. Python supports the object-oriented programming paradigm through classes. They provide an elegant way to define reusable pieces of code that encapsulate data and behavior in a single entity.
