static methods in python

#To create a static method, just add "@staticmethod" before defining it.

>>>class Calculator:
    # create static method
    @staticmethod
    def multiplyNums(x, y):
        return x * y

>>>print('Product:', Calculator.multiplyNums(15, 110))
Product:1650

class Calculator:

    # create addNumbers static method
    @staticmethod
    def addNumbers(x, y):
        return x + y

print('Product:', Calculator.addNumbers(15, 110))

class Calculator:

    def addNumbers(x, y):
        return x + y

# create addNumbers static method
Calculator.addNumbers = staticmethod(Calculator.addNumbers)

print('Product:', Calculator.addNumbers(15, 110))
