在构造函数python中使用私有方法

class MyClass:
    def __init__(self, param1, param2):
        # 构造函数的主要逻辑
        self.param1 = param1
        self.param2 = param2
        self.__init_helper()

    def __init_helper(self):
        # 辅助构造函数的逻辑
        # ...

obj = MyClass(1, 2)

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

    def __init_helper(self):
        # 公共逻辑
        # ...

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

    def __init_helper(self):
        # 子类特有的逻辑
        # ...

obj = MyDerivedClass(1, 2, 3)

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

    def __validate_param(self, param):
        # 参数验证逻辑
        # ...

obj = MyClass(1, 2)
