[PYTHON] Class methods and static methods

class Person(object):

    kind = 'human'

    def __init__(self):
        self.x = 100

    #Methods that can be called without creating an object
    @classmethod
    def what_is_your_kind(cls):
        return cls.kind
    
    #Same as a function outside the class
    @staticmethod
    def about(year):
        print('about human {}'.format(year))

a = Person()
print(a.what_is_your_kind())

#Can be called without creating an object
print(Person.what_is_your_kind())#human
print(Person.about(2020))#about human 2020
