小编use*_*444的帖子

我试图弄清楚Python中的封装.我在shell中进行了一个简单的小测试,看看它是如何工作的,它不像我期望的那样工作.我无法让它发挥作用.这是我的代码:

class Car:
    def __init__(self, carMake, yrMod):
        self.__make = carMake
        self.__yearModel = yrMod
        self.__speed = 0

    #Mutator Methods
    def set_make(self, make):
        self.__make = carMake

    def set_model(self, yrMod):
        self.__yearModel = yrMod

    #def set_speed(self, speed):
        #self.__speed = speed

    #Accessor Methods
    def get_make(self):
        return self.__make

    def get_yearModel(self):
        return self.__yearModel

    def get_speed(self):
        return self.__speed

myCar=Car('Ford', 1968)
myCar2=Car('Nissan', 2012)
myCar.get_make()
'Ford'
myCar.set_make=('Porche')
myCar.get_make()
'Ford'

为什么myCar.set_make没有将福特变成保时捷？谢谢.
