Question

这是我的完整代码：

import random
guessesMade = 0
lives_remaining = 8
roundsPlayed = 0
roundsWon = 0
guessed_letters = ''
words = ['chicken', 'dog', 'cat', 'mouse', 'frog']

def pick_a_word():
    word_position = random.randint(0, len(words) - 1)
    return words[word_position]
    print(pick_a_word())

def play():
    print('Welcome to hangman! The rules are simple: A word will be chosen at random and will be represented by a sequence of blanks. Each blank constitutes a letter in the word. You will be asked to enter a letter and if the letter is contained in the word you will be notified. You can only make an incorrect guess 8 times before you lose the round. To win the round you must guess all the letters and reveal the word. Good luck!\n\n')
    word = pick_a_word()
    while True:
        guess = get_guess(word)
        if process_guess(guess,word):
            print('You won.')
            break
        elif lives_remaining == 0:
            print("\nI'm sorry, but you have run out of guesses. The word was {}.".format(randWord))
            break

def get_guess(word):
    print_word_with_blanks(word)
    print('Lives Remaining: ' + str(lives_remaining))
    guess = input('Guess a letter or the word if you know it.')
    return guess

def print_word_with_blanks(word):
    display_word=''
    for letter in display_word:
        if guessed_letters.find(letter) > -1:
            display_word = display_word + letter
        else:
            display_word = display_word + '-'
    print(display_word)

def process_guess(guess,word):
    if len(guess) > 1 and len(guess == len(word)):
        return whole_word_guess(guess,word)
    else:
        return single_letter_guess(guess, word)

def whole_word_guess(guess,word):
    global guessesLeft
    if guess.lower() == word.lower():
        return True
    else:
        guessesLeft -=1
        return False

def single_letter_guess(guess,word):
    global guessed_letters
    global lives_remaining
    if word.find(guess) == -1:
        lives_remaining -= 0
    guessed_letters = guessed_letters + guess.lower()
    if all_letters_guessed(word):
        return True
    return False

def all_letters_guessed(word):
    for letter in word:
        if guessed_letters.find(letter.lower()) == -1:
            return False
        return True
play()

对于大代码块感到抱歉，但我想查看整个程序以帮助修复我的错误。截至目前，一旦播放被称为播放，它就会在我输入单个字母时不断打印出“剩下的8个生命：”。几个字母之后它只打印出“你赢了”。我很难找到我的错误，蟒蛇专家的任何帮助将不胜感激。

在此功能中：

def print_word_with_blanks(word):
    display_word=''
    for letter in display_word:
        if guessed_letters.find(letter) > -1:
            display_word = display_word + letter
        else:
            display_word = display_word + '-'
    print(display_word)

您忽略了作为参数传入的word，并且循环遍历display_word，这是空的。因此，实际的单词（带空格）根本不会打印出来。

大概你的意思是说：

    for letter in word:
        ...

或者你可以更简洁地写一下：

def print_word_with_blanks(word):
    print(''.join(c if c in guessed_letters else '-' for c in word))

您遇到的另一个问题是：

def all_letters_guessed(word):
    for letter in word:
        if guessed_letters.find(letter.lower()) == -1:
            return False
        return True

这是缩进的方式，它总是在循环的第一次迭代时返回true或false。它应该是这样的：

def all_letters_guessed(word):
    for letter in word:
        if guessed_letters.find(letter.lower()) == -1:
            return False
    return True

所以return True仅在整个循环结束后才会触发。

或者更好的是：

def all_letters_guessed(word):
    return all(c.lower() in guessed_letters for c in word)
