I'm newbie in this editor but it's complex to configure vimrc. I know and understand that everything stay there but I don't understand how to configure, specifically the code. On the other hand, I am writing Python code using Vim. Every time I want to run my code, I type this inside Vim 

:w !python

This gets frustrating, so I was looking for a quicker method to run Python code inside Vim. If somebody can I help me, I would be very grateful.

You've very close. The following works in my config:

nnoremap <F9> :w<cr>:!python %<cr>

First, it enters the command to save the file (:w). Then it tells the shell to have python (!python) run the current file (%).

  • Yes, inside your vimrc. The vimrc file is essentially a list of commands that vim runs whenever it starts up. Therefore, to make this key mapping "stick," it should be entered as a line in the vimrc. [Here's](https://github.com/wbadart/dotfiles/blob/master/.vimrc) my vimrc if you'd like an example. – wbadart Jul 23 '17 at 22:01

  • I'm unable to replicate your error. Could you post a paste/gist/whatever of your full vimrc along with the output of `vim --version`? – wbadart Jul 24 '17 at 16:48
  • I have the version VIM - Vi IMproved 8.0 (2016 Sep 12, compiled Apr 23 2017 12:10:29) Included patches: 1-197, 322, 377-378, 550 and this is my .vimrc file. https://raw.githubusercontent.com/iceiice/.vimrc/master/README.md – iceice Jul 25 '17 at 17:50
  • Do it w/o `shellescape`, as it appears in the response. – wbadart Jul 25 '17 at 17:52
