Autocomplete transitions?

Question

Python

I'm sitting with VIM, because I want to use it when I write in python. Delivered the Jedi-vim plugin to have good autocompletion, and ran into the following problem:
When, for example, I do this:

import math
math.

then auto-completion pops up after the dot (that is, the list of module functions, which is quite expected). However, I can't select the desired method/function (although I'm trying), which is most likely due to the preview of the function, i.e. description of her actions. So, the bottom line is: how can I normally select the function / class / etc. I need in this plugin, but at the same time see a preview of the selected function? That is, after the output occurs, as in the screenshot, I can’t do anything else, and the transition along the arrows does not work.

Answer 1

The solution to the problem is to remove the preview of the autocomplete method/function:
autocmd FileType python set completeopt-=preview

Answer 2

Tried removing python-mode and running VIM without it. And try to write something - nothing has changed.
