Shell没有显示我打印的文本

Question

我正在尝试为我的工作列表创建一个代码，目前我已经编写了以下代码：

list = [ ]

def Menu(choice):
    print("""Menu:


    1.  View entire list

    2.  View one item

    3.  Reset list

    4.  Edit list

    5.  Quit
    """)
    choice = int(input("Please choose an option: "))

while True:
    if choice == "1":
        print (list)
        Menu()

    elif choice == "2":
        oneItem = int(input('Please enter an item to view (1-5): '))
        oneItem = oneItem - 1
        oneView = list[(oneView)]
        print (oneView)
        Menu()

    elif choice == "3":
        list = [None]*6
        Menu()    

    elif choice == "4":
        def carryon():
            for i in range(6):
                add = input("Please enter a new item for the list: ")
                list.append(add)
                carryOn = input("Would you like to carry on? (y/n): ")
                if carryOn == "y":
                    carryon()
                else:
                    break
                break  
        Menu()

在shell中运行代码时，菜单显示良好：

Menu:


1.  View entire list

2.  View one item

3.  Reset list

4.  Edit list

5.  Quit

Please choose an option: 3

但后来就一片空白。我可以在静止状态下输入东西，但什么也没发生。即使我按下回车键，它也会继续。我使用python3.4（gui）
