如何让一个类以特定的顺序接受参数？

class MyClass:
    def __init__(self, param1, param2, param3):
        self.param1 = param1
        self.param2 = param2
        self.param3 = param3

class MyClass:
    def __init__(self, *, param1, param2, param3):
        self.param1 = param1
        self.param2 = param2
        self.param3 = param3

obj = MyClass(param1=value1, param2=value2, param3=value3)

class Params:
    def __init__(self, param1, param2, param3):
        self.param1 = param1
        self.param2 = param2
        self.param3 = param3

class MyClass:
    def __init__(self, params):
        self.param1 = params.param1
        self.param2 = params.param2
        self.param3 = params.param3

params = Params(value1, value2, value3)
obj = MyClass(params)
