在 Python 中编写一个 Hangman 游戏,目的是让玩家猜测一个神秘单词,最多允许 6 次错误猜测。玩家每次输入一个字母,如果这个字母在神秘单词中出现过,则提示玩家「The letter is in the word.」,如果不在神秘单词中出现过,则提示玩家「The letter is not in the word.」并在错误猜测次数上加 1。当错误猜测次数达到 6 次时,游戏结束,计算机获胜,并打印出神秘单词。
然而,在这个 Hangman 游戏中存在一个小问题,即玩家在输入第六个错误猜测时,游戏就会结束,无论这个猜测是否正确。例如,如果神秘单词是「fairy」,玩家输入了「f」,这是正确的猜测,但如果接下来的六个猜测都是错误的,游戏仍然会结束,而不是继续让玩家猜测。
2、解决方案
为了解决这个问题,需要修改游戏中对错误猜测的判断逻辑,使得只有在玩家输入了 6 个错误猜测后游戏才会结束。以下提供两种解决方案:
解决方案一:
# ...省略原有代码...
while guesses < 6:
guess = input("Please enter the letter you guess: ")
if guess in words[i]:
print("The letter is in the word.")
else:
print("The letter is not in the word.")
guesses = guesses + 1 # 错误猜测次数加 1
# 修改了以下代码
if guesses == 6:
print("Failure. The word was:", words[i])
elif guess in words[i]:
print("Congratulations! You guessed the word correctly.")
else:
print("You ran out of guesses. The word was:", words[i])
在上面的代码中,修改了对错误猜测次数的判断逻辑,使得只有在玩家输入了 6 个错误猜测后游戏才会结束并打印出神秘单词。同时,增加了对正确猜测的判断,如果玩家在 6 次错误猜测内猜对了神秘单词,则打印出「Congratulations! You guessed the word correctly.」
解决方案二:
# ...省略原有代码...
incorrect_guesses = 0 # 初始化错误猜测次数
while incorrect_guesses < 6:
guess = input("Please enter a letter to guess: ")
if guess in words[i]:
print('Correct! The letter "' + guess + '" appears in the word ' + str(words[i].count(str(guess))) + ' times.')
else:
print('Sorry, the letter "' + guess +
'" is not in the word.')
incorrect_guesses = incorrect_guesses + 1 # 错误猜测次数加 1
# 修改了以下代码
if incorrect_guesses == 6:
print("Failure. The word was:", words[i])
elif guess in words[i]:
print("Congratulations! You guessed the word correctly.")
else:
print("You ran out of guesses. The word was:", words[i])
在上面的代码中,使用了一个新的变量 incorrect_guesses 来记录错误猜测次数,并将其初始化为 0。然后在 while 循环中,对玩家输入的字母进行判断,如果在神秘单词中出现过,则打印出「Correct! The letter "' + guess + '" appears in the word ' + str(words[i].count(str(guess))) + ' times.」 否则打印出「Sorry, the letter "' + guess + '" is not in the word.」并增加错误猜测次数。
代码例子:
# Hangman 游戏代码
import random
# 创建神秘单词列表
words = ["utopian", "fairy", "tree", "monday", "blue"]
# 随机选择一个神秘单词
secret_word = random.choice(words)
# 初始化错误猜测次数
incorrect_guesses = 0
# 开始游戏循环
while incorrect_guesses < 6:
# 提示玩家输入字母
guess = input("Please enter a letter to guess: ")
# 判断玩家输入的字母是否在神秘单词中出现过
if guess in secret_word:
print('Correct! The letter "' + guess + '" appears in the word ' + str(secret_word.count(str(guess))) + ' times.')
else:
print('Sorry, the letter "' + guess + '" is not in the word.')
incorrect_guesses += 1
# 游戏结束,判断输赢
if incorrect_guesses == 6:
print("Failure. The word was:", secret_word)
elif guess in secret_word:
print("Congratulations! You guessed the word correctly.")
else:
print("You ran out of guesses. The word was:", secret_word)
