我是 Python 中 OOP 的初学者，并且在我的代码中得到“没有足够的值来解包”

Question

class Fruits:

    def __init__(self,name,colour,taste,hasColour): 

        self.name = name

        self.colour = colour

        self.taste = taste

        self.hasColour = hasColour

    def hasAlternateColour(self):

        return self.hasColour

if __name__== "__main__":

    fruitList = []

    print("Enter name, colour, taste of the fruit")

    for itr in range(2):

        name,colour,taste = input().split()

        hasColour = input("Does it have another colour")

        fruitList.append(Fruits(name,colour,taste,hasColour))

    for fruit in fruitList:   

        print(fruit.name,fruit.colour,fruit.taste,fruit.hasAlternateColour(),sep="\t")

输出：

Enter name, colour, taste of the fruit

apple red sweet

Does it have another colour yes

错误：

Answer 1

我的猜测是你已经按下Enter了循环的第二次迭代，只是因为程序没有任何消息就卡住了。您可以替换print为input并将其放入循环中，因此程序将始终以消息停止Enter name, colour, taste of the fruit：：if __name__== "__main__":&nbsp; &nbsp; fruitList = []&nbsp; &nbsp; for itr in range(2):&nbsp; &nbsp; &nbsp; &nbsp; name, colour, taste = input("Enter name, colour, taste of the fruit ").split()&nbsp; &nbsp; &nbsp; &nbsp; hasColour = input("Does it have another colour ")&nbsp; &nbsp; &nbsp; &nbsp; fruitList.append(Fruits(name, colour, taste, hasColour))
