The @classmethod decorator in Python is used to define a class method. A class method is a method that is bound to the class and not the instance of the class. This means that a class method can be called on the class itself, without needing to create an instance of the class.

        The @classmethod decorator is used to indicate that the method is a class method. It is added above the method definition. The first parameter of a class method is always the class itself, conventionally named as "cls".

        Here is an example of using the @classmethod decorator:

class MyClass:
    @classmethod
    def my_class_method(cls, arg1, arg2):
        # This is a class method
        # The first parameter is always the class itself, conventionally named as "cls"
        # The other parameters are regular parameters
        pass

MyClass.my_class_method("arg1", "arg2") # call a class method on the class itself

        In the example above, my_class_method() is defined as a class method using the @classmethod decorator. The first parameter of the method is cls, which is the class itself. This method can be called on the class itself without the need for an instance of the class.
