Omnicomplete with function definitions from documentation

Question

How do I go about showing the description of functions in Vim when using Omnicomplete for Python?

Answer 1

I found a plugin (python-mode) which does the abovementioned, including references, etc. It does not have any dependencies and features a documentation window, and runtime button as well. Link here: https://github.com/klen/python-mode

Thanks everyone!

Answer 2

It is working just out of the box :)

All you need to have:

• vim compiled with +python option.
  You can check it with vim --version. If you are working on Linux, most distributions have this options enabled by default in their packages, or supply enhanced version of vim package (vim-ext, exvim...).
  If you are working on Windows, and then you can download cream which is "A modern configuration of the powerful and famous Vim, ". It is bundled with vim compiled with interesting options, like +python
• then simply open your .py file and type C-x C-o (C is control) when you are in the middle of the word.
  Popup will be triggered and new buffer window will be opend with documentation of the selected completition.

import sys
sys.ver|      # | is a cursor position, press here C-x C-o

You should get completitions for version and version_info
