在Python中比较父类和子类的属性

class ParentClass:
    def __init__(self, parent_property):
        self.parent_property = parent_property

class ChildClass(ParentClass):
    def __init__(self, parent_property, child_property):
        super().__init__(parent_property)
        self.child_property = child_property

parent = ParentClass("Parent Property")
child = ChildClass("Parent Property", "Child Property")

print(isinstance(parent, ParentClass))  # 输出 True
print(isinstance(child, ChildClass))    # 输出 True
print(isinstance(child, ParentClass))   # 输出 True
print(child.parent_property)            # 输出 "Parent Property"
print(child.child_property)             # 输出 "Child Property"

class ParentClass:
    parent_property = "Parent Property"

class ChildClass(ParentClass):
    child_property = "Child Property"

print(issubclass(ChildClass, ParentClass))   # 输出 True
print(issubclass(ParentClass, ChildClass))   # 输出 False
print(ChildClass.parent_property)            # 输出 "Parent Property"
print(ChildClass.child_property)             # 输出 "Child Property"

class ParentClass:
    parent_property = "Parent Property"

class ChildClass(ParentClass):
    child_property = "Child Property"

child = ChildClass()
print(getattr(child, "parent_property"))   # 输出 "Parent Property"
print(getattr(child, "child_property"))    # 输出 "Child Property"
