class method vs static method python 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: class methods in python

from datetime import date

# random Person
class Person:
    def __init__(self, name, age):
        self.name = name
        self.age = age

    @classmethod
    def fromBirthYear(cls, name, birthYear):
        return cls(name, date.today().year - birthYear)

    def display(self):
        print(self.name + "'s age is: " + str(self.age))

person = Person('Adam', 19)
person.display()

person1 = Person.fromBirthYear('John',  1985)
person1.display()

Example 3: class methods in python

@classmethod
def func(cls, args...)

Example 4: 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))
