nano做一个的文本编辑器，偶尔简单修改一下文本还是挺好用的：https://zsxwz.com/2020/04/26/
vim做为一个文本编辑器，比较强大，可以安装各种插件，各种快捷键。自己不太会记快捷键，因此用的也不多。看了很多配置文档，最后还是自己搞一份算了，当做一个ide简单的python环境，很多时候也是很方便的。

使用的是Vundle做为插件管理，如果需要自己添加扩展，就在call vundle#begin()。。。call vundle#end()之间添加插件地址。
按f3 nerdtree文件树：
按f4，nerdcommenter使用#注释当前行。长按\，然后按cu，取消注释。
可以多行注释，按5\cc，向下注释5行。vim自带的在normal模式下:
:5,10 s/^/#/g，用搜索替换的方法注释也是挺好用的。
按f5,运行常见的代码
按f6,Autoformat代码格式化
按ctrl + p，ctrlp.vim模糊搜索
以上快捷键，如果和系统快捷键有冲突，可以根据自己的需求修改。
2、安装扩展，先安装Vundle插件管理：
git clone https://github.com/VundleVim/Vundle.vim.git ~/.vim/bundle/Vundle.vim
终端打开vim，如果报错，先忽略。在normal模式下，:PluginInstall，即可安装扩展。安装过程可能相当的慢，毕竟国内可能没有速度。
YouCompleteMe代码自动补全可能比较麻烦，如果无法补全，就需要自己编译一下：https://github.com/ycm-core/YouCompleteMe
需要自己先安装一下cmake
cd ~/.vim/bundle git clone https://github.com/ycm-core/YouCompleteMe.git cd ~/.vim/bundle/YouCompleteMe ./install.py --clangd-completer
如果下载编译真的很慢，自己大包了一份，放在根目录$HOME/.vim即可。

3、pip安装需要的模块：
pip install pylint autopep8 flake8
