Explain what a static method is in Python and how to use it

A static method in Python is a class method that does not automatically take either the instance of the class (self) or the class itself (cls) as the first argument. It is defined using the @staticmethod decorator.

Such a method is used when a function is logically related to the class but does not depend on the state of a particular object or the class. This is convenient for utility functions that are related to the class but do not require access to its attributes.

Example of usage:

class MathUtils:
    @staticmethod
    def add(a, b):
        return a + b

# Calling the static method
result = MathUtils.add(5, 3)  # 8

Here, add is a static method that can be called without creating an instance of the class.
