How to define classes in Python?

In Python, almost all the code is implemented using classes. Programmers use classes to keep related pieces of code together. This is done using the keyword “class,” which is a collection of object-oriented constructs.

A class is a template for creating objects. Objects have member variables and have behaviour associated with them. In python a class is created by the keyword class.

For example, let's create a simple, empty class with no functions.

>>> class Cars:

... pass

The keyword class is followed by the class name whose first letter is capitalized and then comes a colon to end the class definition and declaration.
