in python, classes are used to create objects, which encapsulate data and behavior. one powerful feature of classes is the ability to define methods, which are functions associated with the class. in this tutorial, we will explore python class methods, their syntax, and how to use them with a detailed code example.
a class method is a method that is bound to the class and not the instance of the class. it takes the class itself as its first argument, conventionally named cls. class methods are defined using the @classmethod decorator.
