我在我的macbook上使用这个：

" configure expanding of tabs for various file types
au BufRead,BufNewFile *.py set expandtab
au BufRead,BufNewFile *.c set expandtab
au BufRead,BufNewFile *.h set expandtab
au BufRead,BufNewFile Makefile* set noexpandtab

" --------------------------------------------------------------------------------
" configure editor with tabs and nice stuff...
" --------------------------------------------------------------------------------
set expandtab           " enter spaces when tab is pressed
set textwidth=120       " break lines when line length increases
set tabstop=4           " use 4 spaces to represent tab
set softtabstop=4
set shiftwidth=4        " number of spaces to use for auto indent
set autoindent          " copy indent from current line when starting a new line

" make backspaces more powerfull
set backspace=indent,eol,start

set ruler               " show line and column number
syntax on               " syntax highlighting
set showcmd             " show (partial) command in status line

（编辑为仅显示与缩进/制表符相关的内容）

我用途：

$ cat ~/.vimrc
syntax on
set showmatch
set ts=4
set sts=4
set sw=4
set autoindent
set smartindent
set smarttab
set expandtab
set number

但我还是要试试达伦的作品

更简单的选项：只需取消注解/etc/vim/vimrc文件中配置的以下部分（最初已注解掉）：

if has("autocmd")
      filetype plugin indent on
    endif

我在python repo中使用了vimrc，其中包括：
http://svn.python.org/projects/python/trunk/Misc/Vim/vimrc
我还加

set softtabstop=4

I have my old config here that I'm updating

确保为VIM编辑正确的配置文件。特别是在使用Windows时，文件可以命名为_vimrc，而不是其他平台上的.vimrc。
体内类型
:help vimrc
并使用以下命令检查_vimrc/.vimrc文件的路径
:echo $HOME
:echo $VIM
确保您只使用一个文件。如果您想将配置拆分成更小的块，您可以从_vimrc文件中获取其他文件。
:help source

结合Daren和Thanos提出的解决方案，我们得到了一个很好的.vimrc文件。

对于更高级的python编辑，请考虑安装simplefold vim插件。它允许您使用正则表达式进行高级代码折叠。我用它来折叠我的类和方法定义，以便更快地编辑。
