Python completion - Feature request

[duytrung]

Problems summary

I'm learning to use Vim/neovim for fun of python programming. I found that it does not show python api completion.

Expected

Cache a full list of python api/method for completion

Environment Information

• OS: win10
• Vim version: 8

Provide a minimal .vimrc with less than 50 lines (Required!)

I don't understand your problem. We have not ESP skills.

[Shougo]

OH, you have installed multiple auto completion plugins.

youcompleteme, neocomplcache, neocomplete, deoplete. You should not mix them. They conflicts.

My recommendation is deoplete.nvim + deoplete-jedi.

@Shougo I've just found this. Your recommendation is for deoplete, but that's neovim, not vim8. Did you intend to recommend: neocomplete, jedi-vim?

What is your issue? Yes, neocomplete and jedi-vim works. My recommendation is deoplete + deoplete-jedi though.
