Python传递基类的参数

class ParentClass:
    def __init__(self, param1, param2):
        self.param1 = param1
        self.param2 = param2

class ChildClass(ParentClass):
    def __init__(self, param1, param2, param3):
        super().__init__(param1, param2)
        self.param3 = param3

# 创建子类对象
child_obj = ChildClass("value1", "value2", "value3")

# 访问父类和子类的参数
print(child_obj.param1)  # 输出: value1
print(child_obj.param2)  # 输出: value2
print(child_obj.param3)  # 输出: value3
