如何在类构造后根据用户输入定义常量值

class MyClass:
    def __init__(self, constant_value):
        self.CONSTANT = constant_value

# 创建类的实例，并传入用户输入的常量值
user_input = input("请输入常量值：")
my_object = MyClass(user_input)

class MyClass:
    CONSTANT = None

    @classmethod
    def define_constant(cls, constant_value):
        cls.CONSTANT = constant_value

    def __init__(self):
        self.define_constant(input("请输入常量值："))

# 创建类的实例，构造函数中会调用类方法来定义常量值
my_object = MyClass()

class MyClass:
    CONSTANT = None

    @staticmethod
    def define_constant(constant_value):
        MyClass.CONSTANT = constant_value

    def __init__(self):
        self.define_constant(input("请输入常量值："))

# 创建类的实例，构造函数中会调用静态方法来定义常量值
my_object = MyClass()
