如何正确设置 Vim 自动缩进以编辑 Python 文件？

I use this on my macbook:

" 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

(edited to only show stuff related to indent / tabs)

Ensure you are editing the correct configuration file for VIM. Especially if you are using windows, where the file could be named _vimrc instead of .vimrc as on other platforms.

In vim type

:help vimrc

and check your path to the _vimrc/.vimrc file with

:echo $HOME

:echo $VIM

Make sure you are only using one file. If you want to split your configuration into smaller chunks you can source other files from inside your _vimrc file.

:help source

for more advanced python editing consider installing the simplefold vim plugin. it allows you do advanced code folding using regular expressions. i use it to fold my class and method definitions for faster editing.

I use the vimrc in the python repo among other things:

http://svn.python.org/projects/python/trunk/Misc/Vim/vimrc

I also add

set softtabstop=4

I have my old config here that I'm updating

I use:

$ 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

But but I'm going to try Daren's entries

A simpler option: just uncomment the following part of the configuration (which is originally commented out) in the /etc/vim/vimrc file:

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

Combining the solutions proposed by Daren and Thanos we have a good .vimrc file.
