class method vs static method code example

Example 1: static methods in python

class Calculator:

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

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

Example 2: What is the difference between static (class) method and instance method?

static or class method
1) A method that is declared as static is known as the static method
2) We don't need to create the objects to call the static methods
3) Non-static (instance) members cannot be accessed in static context 
(static method, static block and static nested class) directly.
4) For example: public static int cube(int n){
return n*n*n*; (multiply *) }

Instance method
1) A method that is not declared as static is known as the instance method.
2) The object is required to call the instance method.
3) Static and non-static variables both can be accessed in instance methods.
4) For example: public void msg() {
...}.

Example 3: static methods in python

class Calculator:

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

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

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