python - KeyError : 'Name' , 有什么问题？

Question

谁能告诉我为什么会出现这个错误？我认为代码没有问题，当我将 **item 替换为 Name,Start,End 时，我仍然无法让它工作

print("To finish input enter nothing.")
Schedule = []
Finish = False
while not Finish:
    Name = input("What is the name of the show?: ")
    Start = input("What time does the show start?: ")
    End = input("What time does the show end?: ")
    Schedule.append({'Name':Name, 'Start':Start, 'End':End})
    print("{0:<10}  |  {1:<10}  -  {2:<10}".format(Name,Start,End))
    print("{Name:<10}  |  {Start:<10}  -  {End:<10}  ".format(**item))
    if len(Name) == 0 or len(Start) == 0 or len(End) == 0:
        Finish = True

Answer 1

你永远不会创建项目。

item = {'Name':Name, 'Start':Start, 'End':End}
Schedule.append(item)
