编写一个程序，从一篇文章里随机取出一个单词，要求用户在有限次数内逐个字母猜测，直到猜到单词中的全部字母或超出次数限制结束游戏

以下是Python代码实现：

import random

# 从文章中随机选择一个单词
article = "Python is a popular programming language. It was created by Guido van Rossum in 1991 and is used for web development, scientific computing, data analysis, artificial intelligence, and more."
words = article.split()
word = random.choice(words).lower()

# 游戏主体
guesses_left = 5
correct_guesses = set()
while guesses_left > 0 and len(correct_guesses) < len(word):
    print("Guesses left:", guesses_left)
    guess = input("Guess a letter: ").lower()
    if guess in correct_guesses:
        print("You already guessed that letter.")
    elif guess in word:
        print("Correct!")
        correct_guesses.add(guess)
    else:
        print("Incorrect.")
        guesses_left -= 1

# 游戏结果
if len(correct_guesses) == len(word):
    print("Congratulations, you guessed the word {}!".format(word))
else:
    print("Sorry, you didn't guess the word {}.".format(word))

游戏规则是：程序随机选择一篇文章，从中选择一个单词作为游戏的目标单词。玩家需要在有限次数内逐个字母猜测，直到猜到单词中的全部字母或超出次数限制结束游戏。在每次猜测后，程序会提示剩余猜测次数以及猜测结果，即是否猜对了其中的一个字母。如果玩家猜对了一个字母，程序会记录下来，并在下一次猜测时提示玩家已经猜过了该字母。如果玩家猜错了一个字母，程序会减少一次剩余猜测次数。如果玩家成功猜出了单词中的所有字母，程序会输出“Congratulations, you guessed the word [目标单词]!”；否则，程序会输出“Sorry, you didn't guess the word [目标单词].”。
