I would like to have an abstract class in which I will have an abstract
property. So I used Pycharm in order to create an abstract (base) class:
import abc
class BaseSomeAbstract(abc.ABC):
_abs_prop = None
@property
@abc.abstractmethod
def abs_prop(self):
return self._abs_prop
@abs_prop.setter
@abc.abstractmethod
def abs_prop(self, value):
self._abs_prop = value
Now I have created a new file and a new class:
from subclassing.abstract.BaseSomeAbstract import BaseSomeAbstract
class ChildSomeAbstract(BaseSomeAbstract):
Now I pressed alt+enter, implement abstract methods. I got only a single choice
abs_prop(self: BaseSomeAbstract).
If I choose this option, my subclass looks like this:
from subclassing.abstract.BaseSomeAbstract import BaseSomeAbstract
class ChildSomeAbstract(BaseSomeAbstract):
@property
def abs_prop(self):
pass
Why Pycharm didn't offer a setter as well as getter?
What is the propper way to define an abstract property, and how to force
subclass to define setter and getter for the abstract property?
