Sublime Text 2 :: Executing Python Code

I am trying to get a code suggestion (drop down box) to suggest it correctly.

Now this is not so. It offers only more or less identifiers and modules that are already in the editable file (which means the area in the file). If, for example, I try this:

import numpy <--- numpy is not suggested when entering text.

numpy.a <--- And here, nothing starts with 'a'.

I have implemented many offers offered on different sites, including the following, but without any success in getting the correct offers with the full code, or sometimes appearing at all:

- Installed SublimeRope
- "use_simple_completion": true  (in SublimeRope.sublime-settings)
- "auto_complete_triggers": [ {"selector": "source.python - string - comment - constant.numeroc", "characters": "."} ]  (in Pyhon.sublime-settings)
- etc.

I'm missing something (of course, I :)). Rate the suggestions.
