用 python 编写的 Hangman 无法识别猜测的正确字母：/

Question

所以我正在做我的第一个项目，这个项目是用 python 编写的，每个项目都像视觉效果和不正确的字母一样工作。但是，它无法识别猜出的正确字母。

import random
from hangman_visual import lives_visual_dict
import string

# random word 

with open('random.txt', 'r') as f:
    All_Text = f.read()
    words = list(map(str, All_Text.split()))
WORD2GUESS = random.choice(words).upper()
letters = len(WORD2GUESS)
print("_" * letters)

word_letters = set(WORD2GUESS)
alphabet = set(string.ascii_uppercase)
lives = 7
used_letters = set()

# user input side 
while len(word_letters) > 0 and lives > 0:
        # letters used
        # ' '.join(['a', 'b', 'cd']) --> 'a b cd'
        print('You have', lives, 'lives left and you have used these letters: ', ' '.join(used_letters))

        # what current word is (ie W - R D)
        word_list = [letter if letter in used_letters else '-' for letter in WORD2GUESS]
        print(lives_visual_dict[lives])
        print('Current word: ', ' '.join(word_list))

        user_letter = input('Guess a letter: ').upper()
        if user_letter in alphabet - used_letters:
            used_letters.add(user_letter)
            if user_letter in WORD2GUESS:
                used_letters.remove(user_letter)
                print('')

            else:
                lives = lives - 1  # takes away a life if wrong
                print('\nYour letter,', user_letter, 'is not in the word.')

        elif user_letter in used_letters:
            print('\nYou have already used that letter. Guess another letter.')

        else:
            print('\nThat is not a valid letter.')

if lives == 0:
    print(lives_visual_dict[lives])
    print('You died, sorry. The word was', WORD2GUESS)
else:
    print('YAY! You guessed the word', WORD2GUESS, '!!')

我试过了，但它仍然无法识别正确的猜测。

        # what current word is (ie W - R D)
        word_list = [letter if letter in used_letters else '-' for letter in WORD2GUESS]
        print(lives_visual_dict[lives])
        print('Current word: ', ' '.join(word_list))

Answer 1

你的错误是这样的：当检查 user_letter 是否在 WORD2GUESS 中时，你错误地将它从 used_letters 中删除，但它必须留在集合中。

在完全猜测单词时，您还缺少一些逃避 while 循环的方法。这可以通过检查 used_letters 是否包含 WORD2GUESS 中的所有字母来在同一地点完成。

是这样的：

import random
from hangman_visual import lives_visual_dict
import string

# random word 

with open('random.txt', 'r') as f:
    All_Text = f.read()
    words = list(map(str, All_Text.split()))
WORD2GUESS = random.choice(words).upper()
letters = len(WORD2GUESS)
print("_" * letters)

word_letters = set(WORD2GUESS)
alphabet = set(string.ascii_uppercase)
lives = 7
used_letters = set()

# user input side 
while len(word_letters) > 0 and lives > 0:
        # letters used
        # ' '.join(['a', 'b', 'cd']) --> 'a b cd'
        print('You have', lives, 'lives left and you have used these letters: ', ' '.join(used_letters))

        # what current word is (ie W - R D)
        word_list = [letter if letter in used_letters else '-' for letter in WORD2GUESS]
        print(lives_visual_dict[lives])
        print('Current word: ', ' '.join(word_list))

        user_letter = input('Guess a letter: ').upper()
        if user_letter in alphabet - used_letters:
            used_letters.add(user_letter)
            if user_letter in WORD2GUESS:
                print('
That is a correct letter.')
                if set(WORD2GUESS).issubset(used_letters):
                    break

            else:
                lives = lives - 1  # takes away a life if wrong
                print('
Your letter,', user_letter, 'is not in the word.')

        elif user_letter in used_letters:
            print('
You have already used that letter. Guess another letter.')

        else:
            print('
That is not a valid letter.')

if lives == 0:
    print(lives_visual_dict[lives])
    print('You died, sorry. The word was', WORD2GUESS)
else:
    print('YAY! You guessed the word', WORD2GUESS, '!!')
