while循環應停止時重復一次

Question

當option =“ e”時，此while循環應停止，但是當option =“ e”時，它將以某種方式將option設置為“”（我已經通過調試器進行了檢查）並再次運行（盡管option =“”）不在while循環，僅當您將選項設置為等於“ e”兩次時，它才會停止。 Option不是全局變量，因此功能無法更改其值。

我已經嘗試過使用while True：和option =“ e”時的break命令，但是它不會脫離循環

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.")

如果要求我“輸入n來發新手，r播放最后一手，或e結束游戲”，當我鍵入“ e”（不帶引號）時，我希望它會跳出循環。

檢查這是否是您所期望的。 我試圖重新創建上述錯誤，但無法重新創建。 讓我知道您是否再得到它。

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.")
