我是编程新手。 我必须为我的编程类编写一个Rock Paper Scissors游戏。我有一个很好的开始，但有些问题我不知道如何解决。
我需要三种不同的菜单。主菜单应询问1.开始新游戏2.加载游戏或3.退出。选择1或2，然后输入您的姓名，然后开始播放。然后要求您选择1. Rock 2. Paper 3. Scissors。我的游戏效果很好但是在选择了Rock paper剪刀后我想要一个新的菜单弹出：你想做什么？ 1.再次播放2.查看统计数据3.退出。但我不知道在哪里放这个。我尝试了几个不同的地方，但它只是通过它并再次要求石头剪刀。
然后我的第二个问题是，当用户选择1.状态新游戏需要询问他们的名字并使用他们的名字将他们的游戏保存到文件中。然后，当用户选择2.加载游戏时，他们的名字将用于查找文件“name.rps”并加载他们的统计数据以继续播放（统计数据，轮数，名称）。
感谢任何帮助。

updateScoreBoard(outcome)

这是我们想要的方法。
所以你需要做的就是调用updateScoreBoard()下的新菜单方法。
然后在新的菜单方法下。
if(playerChoice == 1)
play();
if else(playeChoice == 2)
stats();
else
quit();

使用'%s.rsp' % name，而不是'name.rsp'。 open('name.rsp', 'w')将永远打开“name.rsp＆＃39; evn如果名字=＆＃39; foo＆＃39;。
