### Python 编写背单词记单词小程序完整源码示例 #### 小程序功能描述 该程序旨在帮助用户记忆单词。通过随机选取单词并让用户猜测其含义的方式，增强用户的词汇量。程序会显示当前单词的状态以及错误次数，并允许玩家逐个字母地进行猜测。 ```python import random def load_words(file_path): """加载单词文件""" with open(file_path, 'r', encoding='utf-8') as file: words = [line.strip() for line in file.readlines()] return words def choose_word(words_list): """从列表中随机选择一个单词""" word_to_guess = random.choice(words_list).lower() guessed_letters = set() attempts_left = 6 while True: display_state(word_to_guess, guessed_letters) if all(letter in guessed_letters or letter not in "abcdefghijklmnopqrstuvwxyz" for letter in word_to_guess): print("\n恭喜你赢了！") break guess = input("请输入一个字母作为猜测: ").strip().lower() if len(guess) != 1 or not guess.isalpha(): print("无效输入，请重新尝试。\n") continue elif guess in guessed_letters: print(f"已经猜过 {guess} ，请再试一次\n") else: guessed_letters.add(guess) if guess not in word_to_guess: attempts_left -= 1 if attempts_left == 0: print(f"\n很遗憾，机会已用尽。正确答案是 '{word_to_guess}' 。") break else: print(f"{attempts_left}次剩余机会...\n") def display_state(word, letters_guessed): """展示当前游戏状态""" masked_word = ''.join([char if char.lower() in letters_guessed or char not in "abcdefghijklmnopqrstuvwxyz" else '_' for char in word]) print(f'当前进度：{masked_word}') if __name__ == "__main__": WORDS_FILE_PATH = './words.txt' try: words = load_words(WORDS_FILE_PATH) choose_word(words) except FileNotFoundError: print(f"无法找到指定路径下的单词文件 ({WORDS_FILE_PATH})") ``` 此段代码实现了基本的猜词游戏逻辑[^1]。为了使这个小游戏更加完善，还可以考虑加入更多特性，比如增加难度级别选项、记录最高分等功能。
