I discovered this trick while trying to do some quick investigation in Vim, and
not wanting to have to leave the editor, found a way to quickly replace Python
code (or anything you can pipe to an external command) with it's output in Vim.
What you do is, write the code inside a buffer, then select it in visual mode.
Once it's selected, press : and you will get Vim's
:'<,'> range, which
means all the text between the beginning and end of the visual cursor.
