如何在对象的链式调用中添加变量int？

class MyClass:
    def __init__(self):
        self.value = None

    def set_value(self, value):
        self.value = value
        return self

    def do_something(self):
        # 在这里使用self.value进行操作
        return self

my_obj = MyClass()
my_obj.set_value(10).do_something()

class MyClass:
    def __init__(self):
        self.value = None

    def set_value(self, value):
        self.value = value
        return self

    def do_something(self):
        # 在这里使用self.value进行操作
        return self

my_obj = MyClass()
my_obj.set_value(10).do_something()

class IntContext:
    def __init__(self, value):
        self.value = value

    def __enter__(self):
        return self.value

    def __exit__(self, exc_type, exc_val, exc_tb):
        pass

class MyClass:
    def do_something(self):
        # 在这里使用int值
        return self

my_obj = MyClass()
with IntContext(10) as value:
    my_obj.do_something()
