Running blocks of code inside vim

I recently added the following code in the .vimrc:

" Runs python inside vim
  autocmd FileType python nnoremap <buffer> <F9> :exec '!clear; python' shellescape(@%, 1)<cr>

which allows me to run the entire python script from inside vim when pressed the F9 key. Nevertheless, several times I do not want to run the entire python script but just one line or even a block of lines. I googled in searching for these behavior but could not find any solution that worked, at least for me.

Someone can help me on this?

Thanks

First you should make a function to get your visually selected text. I brought it from https://stackoverflow.com/a/6271254/3108885:

function! s:GetVisualSelection()
  let [lnum1, col1] = getpos("'<")[1:2]
  let [lnum2, col2] = getpos("'>")[1:2]
  let lines = getline(lnum1, lnum2)
  let lines[-1] = lines[-1][:col2 - (&selection == 'inclusive' ? 1 : 2)]
  let lines[0] = lines[0][col1 - 1:]
  return join(lines, "\n")
endfunction

Then, add an autocmd for Visual mode.

autocmd FileType python vnoremap <buffer> <F9> :<C-U>exec '!clear; python -c' shellescape(<SID>GetVisualSelection(), 1)<CR>

Note that <C-U> is for cleaning '<,'> things when : is pressed on Visual mode. Also we use python -c to pass a program as a string.
