Overview of built-in decorators in Python class

Explain how standard decorators applied to class methods work, and demonstrate their usage both through the class itself and through its instance.

class Sample:
    value = 1

    @classmethod
    def cls_meth(cls, a):
        return cls.value + a

    @staticmethod
    def stc_meth(a):
        return a * a

    @property
    def prop(self):
        return self.value

Sample.cls_meth(1)
Sample.stc_meth(1)
Sample().prop

s = Sample()

s.cls_meth(1)
s.stc_meth(1)
s.prop

(Note: The original code had an error in the property method definition; it should not have parameters other than self.)
