Vim n Python 환경설정

Very likely, your source file contains both tabs and spaces.
It's a good pratice to only use spaces in source file.
You can convert all tabs to spaces by using those command:

:set expandtab:ret!

I suggest put those commands bellow in your .vimrc:

set expandtab softtabstop=4 tabstop=4 shiftwidth=4

_vimrc

autocmd BufRead,BufNewFile *.py syntax on
autocmd BufRead,BufNewFile *.py set ai
autocmd BufRead *.py set smartindent cinwords=if,elif,else,for,while,with,try,except,finally,def,class
