How to set :!python3 to :!python in vim?

Question

To run a script using python3+ in vim (having Python2.7 as default), you need to type:

:!python3 <filename.py>

Technically, how do you run it with Python3+ with just:

:!python <filename.py>

An alias perhaps, just to shorten it.

You ca n use aliases, read: http://stackoverflow.com/a/4642855/1005215 — Nehal J Wani, Aug 20 '16 at 06:09
How about just symlink `/usr/local/bin/py` to `/usr/bin/python3` ;) — Antti Haapala -- Слава Україні, Aug 20 '16 at 06:15

cnoremap !py !python3<Space>

This would substitute !py with !python3 anywhere on the command line.

It is perhaps better than using cnoremap py python3<Space> as !py would not be as common as possibility of py on the command line

Also, you might notice vim waiting a few moments whenever you type ! on the command line. You can continue typing regardless

'cnoremap' can do the trick. But I find the link in the comments section the most useful in my case. Thanks anyway. – Van Aug 20 '16 at 07:49

If you're writing a lot of python consider using map instead of remapping names of applications in vim only. Using map will probably save you a few key strokes and it will make what's happening more explicit. ctrl+shift+p seems like a good option. Of course, you'll change that to whatever works better in your own flow.

  map <C-S-p> :!python3<Space>
