我的猜測是你已經按下Enter了循環的第二次迭代，只是因為程序沒有任何消息就卡住了。您可以替換print為input并將其放入循環中，因此程序將始終以消息停止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))
