while 循环在应该停止时重复一次

Question

这个 while 循环应该在 option = "e" 时停止，但是当 option = "e" 它以某种方式将 option 设置为 ""（我已经用调试器检查过）并再次运行（尽管 option = ""）是在 while 循环之外，它仅在您将选项设置为“e”两次时才会停止。 Option 不是全局变量，因此函数无法更改其值。

我已经尝试使用 while True: 和一个 break 命令 when option = "e" 但它没有跳出循环

option = ""
hand = {0:0}
while option != "e":
    option = input("Enter n to deal a new hand, r to replay the last hand, or e to end game: ")
    if option == 'n':
        hand = dealHand(HAND_SIZE)
        playHand(hand,wordList,HAND_SIZE)
    elif option == 'r':
        if 0 in hand:
            print("You have not played a hand yet. Please play a new hand first!","\n")
        else:
            playHand(hand,wordList,HAND_SIZE)
    elif option != "e":
        print("Invalid command.")

如果我输入“e”（不带引号），当它要求我“输入 n 处理新手，r 重玩上一手，或 e 结束游戏：”时，我希望它能够跳出循环

检查这是否是您所期望的。我试图重新创建上述错误，我无法重新创建它。如果你再次得到它，请告诉我。

option = ""
hand = {0:0}
while True:
    option = input("Enter n to deal a new hand, r to replay the last hand, or e to end game: ")
    if option == 'n':
        hand = dealHand(HAND_SIZE)
        playHand(hand,wordList,HAND_SIZE)
    elif option == 'r':
        if 0 in hand:
            print("You have not played a hand yet. Please play a new hand first!","\n")
        else:
            playHand(hand,wordList,HAND_SIZE)
    elif option == "e":
        break
    elif option != "e":
        print("Invalid command.")
