打卡记录

Part 2 作业:

A. 游戏要求:

  1. 程序必须从 words.txt 文件中随机挑选一个单词。hangman.py 文件中已经实现了加载单词列表 和 随机选择单词 的功能。
  2. 用户一开始有6次机会
  3. 游戏一开始,提示用户有单词中有多少个字母,提示用户的机会次数。
  4. 程序需要判断用户还有哪些字母可以猜

B. 用户交互:

The game must be interactive and flow as follows:

  1. 每次在用户猜测之前,你需要显示以下信息:
    a. 提示用户所剩的次数
    b. 还有哪些字母用户还没有猜测
  2. 提示用户每次只能猜一个字母
  3. 每次等用户输入后,需要告诉用户所输入的单词是否在单词中
  4. 等用户输入后,你还需要显示结果,哪些才对哪些还没有猜到,使用下划线来标识没有猜到的字母位置。
  5. 最后,输出(­­­­­)符号,用户区分每一轮游戏

C. 用户输入要求:

  1. 你可以假设用户每次只输入一个字符,但用户也许会输入数字、特殊符号、字母,你的程序只接收小写字母
  2. 如果用户输入了字母意外的内容,你需要告诉用户只能输入字母。每当用户输入非字母字符、或者已经输入过的字母,将会减少一次警告的机会,如果没有了警告机会,游戏就会结束。

可以灵活运用一下函数:

  • str.isalpha(‘your string’)
  • str.lower(‘Your String’)

D. 游戏规则

  1. 初始【警告次数【为3
  2. 如果用户输入了非字母的内容,【警告次数】减一;没有警告次数,游戏失败
  3. 如果用户输入了已经输入过的内容,【警告次数】减一 ;
  4. 辅音:如果用户输入了辅音字母,且没有猜中,【猜测机会】减1
  5. 元音:如果用户输入的原因字母,没有猜过,且没有猜中,【猜测机会】减2

E. 游戏终止条件

  1. 当用户猜对了所有字母 或者 次数消耗完时终止游戏
  2. 次数消耗完并且没有完成字母,告诉用户结果并显示正确的字母。
  3. 用户赢了的话,输出恭喜信息,并显示用户分数
  4. Total score = guesses_remaining* number unique letters in secret_word(总分 = 剩余猜测次数 x 单词字母数(去重))
