列表索引运行出来了吗？ Python

Question

我正在制作一个解码器，但是当我输入一个代码字时，如果该代码字不在我在列表中输入的最后一个代码字之后，它会抛出一个错误

代码：

CodeNum = 0
while RTs < 9:
        CodeWord = str(input("Code-word: "))
        Stop = ["Stop", "Exit", "End", "Terminate"]
        if CodeWord in Stop:
            break
        while CodeNum < 55:
            if CodeWord == CodeWordsUpC[CodeNum]:
                output.append(LettersUpC[CodeNum])
                break
            else:
                CodeNum = CodeNum + 1
        RTs = RTs + 1

错误：

Traceback (most recent call last):
  File "/home/pi/mu_code/Encoder_Decoder.py", line 97, in <module>
    if CodeWord == CodeWordsUpC[CodeNum]:
IndexError: list index out of range

LettersUpC = ["Q", "W", "E", "R", "T", "Y", "U", "I", "O",
              "P", "A", "S", "D", "F", "G",
              "H", "J", "K", "L", "Z", "X", "C", "V", "B", "N", "M", "<",
              ">", "_", ": ", "-"]

我忘记的是我需要将 'CodeNum' 重置为 0

output = [":", ]
RTs = 0
InOrOut = str(input("Encode or Decode, E/D: "))
if InOrOut == "D":
    while RTs < 9:
        CodeNum = 0
        CodeWord = str(input("Code-word: "))
        Stop = ["Stop", "Exit", "End", "Terminate"]
        if CodeWord in Stop:
            break
        while CodeNum < 55:
            if CodeWord == CodeWordsUpC[CodeNum]:
                output.append(LettersUpC[CodeNum])
                break
            else:
                CodeNum = CodeNum + 1
        RTs = RTs + 1
    print(str(output[1] + output[2] + output[3]
              + output[4] + output[5] + output[6]
              + output[7] + output[8]))

现在可以使用了，谢谢 Karl Knechtel！
