使用Python编写的简单游戏案例：猜单词游戏

下面是一个使用Python编写的简单猜单词游戏的案例，该游戏会随机从一个单词列表中选取一个单词，玩家需要根据提示猜出正确的单词。以下是完整的代码及其使用示例。

import random

def get_word():
    words = ["apple", "banana", "orange", "watermelon", "mango"]
    return random.choice(words)

def play_game():
    word = get_word()
    guessed_letters = []
    attempts = 6

    while True:
        print("
Word: ", end="")
        for letter in word:
            if letter in guessed_letters:
                print(letter, end=" ")
            else:
                print("_", end=" ")
                
        if set(word) == set(guessed_letters):
            print("
Congratulations! You guessed the word correctly!")
            break
            
        if attempts == 0:
            print("
Game over! You failed to guess the word. The word was", word)
            break

        print("
Attempts remaining:", attempts)
        guess = input("Enter a letter: ").lower()

        if len(guess) > 1:
            print("Please enter only one letter at a time!")
            continue

        if guess in guessed_letters:
            print("You have already guessed that letter!")
            continue

        guessed_letters.append(guess)

        if guess not in word:
            attempts -= 1
            print("Incorrect guess!")

play_game()

使用示例：

Word: _ _ _ _ _

Attempts remaining: 6
Enter a letter: a

Word: a _ _ _ _

Attempts remaining: 6
Enter a letter: e

Word: a _ _ _ _

Attempts remaining: 5
Enter a letter: p

Word: a p p _ _

Attempts remaining: 5
Enter a letter: l

Congratulations! You guessed the word correctly!
