  • ERROR: class attr 에 함수를 지정하고 self.attr로 부를경우 class 가 함수 args 로 들어간다.

    • SITUATION: class attr 에 함수를 지정하고 self.attr로 부를경우 class 가 함수 args 로 들어간다.

      • code

        import abc
from typing import Callable, TypeVar, Any

class Discriminator(abc.ABC):
def *init*(self, comp_value: list) -> None:
self.comp_value = comp_value

def descriminate(self, value):
return self.dis_func(value)

def dis_func(self, val):
raise NotImplemented


class DiscriminatorMixin:

def is_in_another(*vals):

\# return val in val2

user_discr = UserNameDiscriminator([1,2,3,4])

user_discr.descriminate(3)```

    • REASON:

      • instance method 가 아닌 attribute: Callable 를 call 하면 class method로 취급한다.

    • SOLUTION:

      • 함수에 @classmethod decorator 를 달아주고 class attr에 assign 한다.
