如何在Python中键入用于多个子类的方法的修饰符

class ParentClass:
    @classmethod
    def class_method(cls):
        print("This is a class method.")

class ChildClass(ParentClass):
    pass

ChildClass.class_method()  # 调用类方法

class ParentClass:
    @staticmethod
    def static_method():
        print("This is a static method.")

class ChildClass(ParentClass):
    pass

ChildClass.static_method()  # 调用静态方法

class MyClass:
    def __init__(self):
        self._value = 0

    @property
    def value(self):
        return self._value

obj = MyClass()
print(obj.value)  # 访问属性

class MyClass:
    def __init__(self):
        self._value = 0

    @property
    def value(self):
        return self._value

    @value.setter
    def value(self, new_value):
        self._value = new_value

obj = MyClass()
obj.value = 10  # 设置属性值
print(obj.value)  # 访问属性

from abc import ABC, abstractmethod

class MyAbstractClass(ABC):
    @abstractmethod
    def abstract_method(self):
        pass

class MyConcreteClass(MyAbstractClass):
    def abstract_method(self):
        print("This is an implementation of abstract_method.")

obj = MyConcreteClass()
obj.abstract_method()  # 调用抽象方法的实现
