Why can I do this?
from abc import ABCMeta, abstractmethod
class AbstractClass(object):
_metaclass__ = ABCMeta
@abstractmethod
def foo():
pass
@abstractmethod
def bar():
pass
class ConcreteClass(AbstractClass):
pass
a = AbstractClass()
nb = ConcreteClass()
There is no error. Everything runs perfectly. Why can I instantiate an abtract class and why can I instantiate an object of ConcreteClass though it did not implement abstract methods?
You are missing a _
__metaclass__ = ABCMeta
