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__":

    fruitList = []

    for itr in range(2):

        name, colour, taste = input("Enter name, colour, taste of the fruit ").split()

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

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