怎么使用python的turtle开发一个打字游戏呢？ 然后通过此游戏提高键盘输入的速度。
本文就开发一个这样的打字游戏，用户根据屏幕上掉下来的字母，快速敲出正确的字母，正确率越高，得分越高，如果字母到达屏幕底部你还没有敲出来，则整个游戏结束。
开发思路根据设定的字母数N，随时都有N个随机的字母从屏幕上掉下来。当你从键盘上敲出一个正确的字母时，这个字母就会消失，取而代之的是一个从顶部随机掉落的新字母。同时，你的分数也会增加1分。当你击中一个错误的字母时，你的分数将减少1分。
为了增加游戏的难度，这些字母以随机的速度下落，也让字母下落的速度随着时间的推移逐渐增加。
当有字母到达屏幕底部你还没有敲出来，则整个游戏结束
