A property allows you to define an attribute of your object. It works on instances.
A classmethod operates on the class independent of any instance.
Examples are helpful:
class A:
_name = 'foo'
@classmethod
def print_name(cls):
print(cls._name)
@property
def name(self):
return self._name
# print the default class name
A.print_name() #foo
# create an instance, change its name, print it
a = A()
a._name = 'bar'
print(a._name) #bar
# classmethod does not see instance data
a.print_name() #foo
# class name is unchanged by instances
A.print_name() #foo
