Python文字游戏问题

所以我正在看一个python教程如何创建hangman最近。我试过了，但它有一些问题与源代码，所以我一直试图写类似的代码，工作良好。我最近才遇到一个问题。基本上，当你猜出'secret'字符串中的最后一个字母时，它不会用该字母替换空白。我想知道为什么会发生这种情况，我该如何解决它。

下面是代码

import random
words = '''aardvark baboon calf camel deer dingo alligator ant jackal iguana 
falcon flamingo macaw manatee marmoset flee emu narwhal leopord ocelot 
lemming opossum dog dolphin dove beaver bison wallaby rabbit salamander 
seagull sheep skunk tiget tortoise unicorn dragon zombie'''.split()
def randomWord(wordList):
    wIndex = random.randint(0, len(wordList) - 1)
    return wordList[wIndex]
def displayGame(wrong, right, secret):
    print('Wrong Guesses:', end=' ')
    for letter in wrong:
        print(letter, end=' ')
    print()
    blanks = '_' * len(secret)
    for i in range(0, len(secret) - 1):
        if secret[i] in right:
            blanks = blanks[:i] + secret[i] + blanks[i+1:]
    for letter in blanks:
        print(letter, end=' ')
    print()
def getGuess(guessed):
    while True:
        guess = input()
        guess = guess.lower()
        if len(guess) != 1:
            print('Please enter a single letter.')
        elif guess in guessed:
            print('You have already guessed that letter.')
        elif guess not in 'abcdefghijklmnopqrstuvwxyz':
            print('Please print a letter.')
        else:
            return guess
def playAgain():
    print('Would you like to play again? (yes or no)', end=' ')
    while True:
        keepGoing = input()
        if keepGoing == 'yes':
            return True
        elif keepGoing == 'no':
            return False
        else:
            print('Yes or no please.')

print('Guessing Game!')
print()
wrong = ''
right = ''
secret = randomWord(words)
gameOver = False
while True:
    while gameOver == False:
        displayGame(wrong, right, secret)
        guess = getGuess(wrong + right)
        if guess in secret:
            right += guess
            foundAll = True
            for i in range(0, len(secret) - 1):
                if secret[i] not in right:
                    foundAll = False
                    break
            if foundAll:
                print('Congratulations! You won! The word was ' + secret)
                gameOver = True
                break
        else:
            wrong += guess
            if len(wrong) > 7:
                print('You ran out of guesses! Game over! The word was ' + secret)
                gameOver = True
                break
    keepGoing = playAgain()
    if keepGoing:
        wrong = ''
        right = ''
        secret = randomWord(words)
        gameOver = False
    else:
        print('Thanks for playing!')
        break

这里是破碎的输出
