Python说一个特定的项目在一个空的列表中

我正在尝试制作一个刽子手游戏。我有一个功能，如果你选择的字母在所有猜测的字母列表中，它会告诉你它已经被猜测了。当我运行这个程序时，它会说这个字母已经猜到了，即使它没有被猜到，或者它是我猜到的第一个字母

import random
print("---Hangman---")
WordList = ["programming", "computer", "game"]
LetterList = []
Word = random.choice(WordList)
NumberOfLetters = len(Word)
print("There are", NumberOfLetters, "letters in the word.")


for i in range (NumberOfLetters):
    print("Guess a letter:")
    LetterGuess = input()
    LetterList.append(LetterGuess)
    if LetterGuess in LetterList:
        print("You already guessed that letter")
    elif LetterGuess in Word:
        print("Correct")
        print("You now have the correct letters: ", LetterList)
        i += 1
    elif LetterGuess not in Word:
        print("Wrong")
        print("You have the correct letters: ", LetterList)

当我猜一个数字时，它是这样说的：

 ---Hangman---
There are 11 letters in the word.
Guess a letter:
d
You already guessed that letter

---

您将猜测添加到列表中，然后立即检查它是否存在

LetterList.append(LetterGuess)
if LetterGuess in LetterList:

---

好的，我现在明白了，谢谢！
