Python 如何在能够调用函数的同时使函数可调用,python,object,Python,Object,我正在做一个游戏，想为我的对象创建一个对象类，但也决定稍微推动一下我自己，现在我遇到了一个障碍因此，我希望函数能够被调用，同时能够像目录一样使用它。我不希望get/set函数干扰get/set类示例： obj.position.get() obj.position.get.x() class Object: def __init__(self, x, y, width, height): self.__x = x self.__y = y

我正在做一个游戏，想为我的对象创建一个对象类，但也决定稍微推动一下我自己，现在我遇到了一个障碍

因此，我希望函数能够被调用，同时能够像目录一样使用它。我不希望get/set函数干扰get/set类

示例：

obj.position.get()
obj.position.get.x()

class Object:
    def __init__(self, x, y, width, height):
        self.__x = x
        self.__y = y
        self.__width = width
        self.__height = height
        self.size = self.__Size(self)
        self.position = self.__Position(self)

    class __Size:
        def __init__(self, outer):
            self.__outer = outer
            self.get = self.__get(self.__outer)
            self.set = self.__set(self.__outer)

        # Trying to make the two functions below work without interfering with the __get and __set classes

        def get(self):
            return self.__outer.__width, self.__outer.__height

        def set(self, width, height):
            self.__outer.__width = width
            self.__outer.__height = height

        class __get:

            def width(self):
                return self.__outer.__width

            def height(self):

        class __set:
            def __init__(self, outer):

            def height(self, height):
                self.__outer.__height = height


    class __Position:

你所拥有的是痛苦的复杂。使用组合不需要嵌套类

class Size:
    def __init__(self, width, height):
        self.width = width
        self.height = height


class Position:
    def __init__(self, x, y):
        self.x = x
        self.y = y


class Object:
    def __init__(self, size, pos):
        self.size = size
        self.pos = pos

    @classmethod
    def from_scratch(cls, x, y, width, height):
        return cls(Size(x,y), Position(width, height))


obj1 = Object(Size(3, 5), Position(0,0))
obj2 = Object.from_scratch(9, 22, 10, 5)

obj1_location = obj1.position
obj2_size = obj2.size

为什么要有一个

\u get

和

\u set

类呢？类嵌套通常是个坏主意，而三类嵌套更糟糕！为了使

obj.position.get（）

和

obj.position.get.x（）

都能工作，

get

必须是一个可调用的对象。这意味着，无论

obj.position.get

有什么类型，它都应该定义

\uuu调用

方法来定义get（）
的含义。为什么要有\uu get
和\uu集
