当我尝试实例化类时，例如：

class Fridge:
    def __init__ (self, food, quantity):
        self.food=food
        self.quantity=quantity
    def UserEntry(self):
        if input=="milk":
            print("you got milk!")
        else:
            print ("What do you want?")
    def DisplayFridge(self):
        print("Fridge_item#1 :" , self.food, "Quantity:" , self.quantity)

并且只要我打开括号以实例化如下的类：

test= Fridge

我看到了传递给类构造函数/初始化方法的参数。（即食物和数量）。

考虑到这一点......我有点不知道为什么我没有得到任何输出。我也被要求输入等等。

Answer 1

你没有这样输入，你应该尝试：

class Fridge:
    def __init__ (self, food, quantity):
        self.food=food
        self.quantity=quantity
    def UserEntry(self):
        var = raw_input("Please enter something: ")
        if var=="milk":
            print("you got milk!")
        else:
            print ("What do you want?")
    def DisplayFridge(self):
        print("Fridge_item#1 :" , self.food, "Quantity:" , self.quantity)

但是你的代码中缺乏逻辑：

为什么从不使用UserEntry？
你如何使用冰箱？
您的userEntry方法永远不会更改您的self.food变量。

Answer 2

如果您正在制作实例，请键入

test = Fridge(

然后它不会向您显示“传递给类构造函数/初始化方法的参数”，但它会向您显示为了创建实例而必须传递的内容。 / p>

E.g。

test = Fridge("milk", 10)

现在它持有10个奶。尝试

test.UserEntry()
test.DisplayFridge()
