python如何在子类中初始化值？

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

class ChildClass(ParentClass):
    def __init__(self, parent_value, child_value):
        super().__init__(parent_value)
        self.child_value = child_value

# 创建子类对象并初始化值
child_obj = ChildClass("Parent Value", "Child Value")
print(child_obj.parent_value)  # 输出：Parent Value
print(child_obj.child_value)  # 输出：Child Value
