Mar 25, 2020 · Python is an object-oriented programming language that is ideal for creating reusable patterns of code. An important concept in Python is to distinguish classes and objects: A class is a blueprint created by a programmer for an object. This defines the logic for attributes and methods that can characterize an object instantiated from this class.

In Python, we use classes to create objects. A class is a tool, like a blueprint or a template, for creating objects. It allows us to bundle data and functionality together. Since everything is an object, to create anything, in Python, we need classes. Let us look at the real-life example to understand this more clearly.
