电脑shift键失灵,用python程序解决了

#Python

好好的DELL笔记本电脑两个shift键莫名其妙的坏了, 真是痛苦,基本上都不能用啦, 大小写还好说。 @!#¥%*+_()^$%,这些字符也不能用啦。

想到个方法, 我有两个ALT键是好的, 能不能把其中一个变成SHIFT键?网上看了看,居然有大咖写好了python的程序解决了我的问题。 我把左ALT键变成了左SHIFT键,解决了我的燃眉之急。

下面把这段神codings,分享给大家。

先自己写个txt,命名叫test.txt文件,写入:
Left Shift: Left Alt;
Left Alt: Left Shift;

把文章最下面这段python代码写入.py文件, 保存文件比如为 layout.py。将你的test.txt和layout.py放在同一目录下,在python IDE运行:
python layout.py test.txt
运行后, 生成一个layout_bat文件夹, 进入点击.bat文件右键,以管理员身份运行,就可以写入注册表,重启电脑后就可以了。
下次如果万一你的电脑键盘某个字母不好用, 也试试这个方法吧!
