IT professional but interested in teaching english and hindi

cls accepts the class Person as a parameter rather than Person's object/instance. Now, we pass the method Person. printAge as an argument to the function classmethod . This converts the method to a class method so that it accepts the first parameter as a class (i.e. Person).
