'include=^\s*\(from\|import\)' error in vim

Question

When I type :set inc it doesn't work and below status bar shows include=^\s*\(from\|import\). Even when I turn on GVim it shows include=^\s*#\s*include error.

Here is my .vimrc file

set nocp
filetype plugin indent on
set hls inc ar ai wrap lbr nu rnu et magic sc acd aw sb spr mouse=a sw=4 sts=4 ts=4 ls=2 bs=indent,eol,start

This is expected. You're simply asking Vim what the 'include' option (short name 'inc') is currently set to.

When you use :set with an option that takes a value but don't include any =s, Vim will simply tell you what that option is set to, which is what you're seeing here.

From our discussion in comments, we established you were actually trying to enable 'incsearch' instead, which you can do with:

set incsearch

Or you can shorten it to:

set is
