Python实现Hangman游戏时try again重试选项失效问题求解

• 核心问题：end_of_game 变量在全局位置仅初始化一次，第一局游戏失败后该变量被设为 True，外层重试循环开启新一局时没有重置该值，导致内层的游戏主循环 while not end_of_game 直接跳过执行，程序进入无输出的空转状态。
• 逻辑遗漏：重试询问的代码放在内层游戏循环的生命值判断分支内，仅在失败场景触发，没有覆盖玩家获胜后的重试场景。
• 冗余执行：判定游戏失败后仍会执行单词拼接打印、绞刑架绘制的多余逻辑。

• 每启动新一局游戏时，在内层游戏循环启动前将 end_of_game 重置为 False，保证游戏主循环可以正常运行。
• 将重试询问逻辑移到内层游戏循环结束后，无论玩家是获胜还是失败，都统一触发重开询问，避免逻辑遗漏。
• 调整代码执行顺序，游戏状态判定为结束后不再执行多余的输出逻辑。
