I'm implementing a meta class as follows:
from abc import ABCMeta
class Algorithm(metaclass=ABCMeta):
# lots of @abstractmethods
# Non-abstract method
@property
def name(self):
''' Name of the algorithm '''
return self.__class__.__name__
class MyLittleAlgorithm(Algorithm):
def magic(self):
return self.name
Then, I'm under the impression that the following two prints ought to give the same result.
a = MyLittleAlgorithm()
print(a.magic)
print(a.name)
but in fact I get:
>>> print(a.magic)
<bound method MyLittleAlgorithm.magic of <__main__.MyLittleAlgorithm object at 0x11242f438>>
>>> print(a.name)
MyLittleAlgorithm
The behaviour I'm after is the latter one. (I want every algorithm which inherits from Algorithm to have a .name @property which it can use to refer to itself.)
Please note that I do not want to instantiate the meta class. I merely want the instances of the children of it to have the .name @property without me having to write out the code for each one explicitly.
