I tried pydiction  didn t work for me  and the normal omnicompletion  too limited   I looked into Jedi as suggested but found it too complex to set up  I found python-mode  which in the end satisfied my needs  Thanks  klen

As pointed out by in the comments  this answers is outdated  youcompleteme now supports python3 and jedi-vim no longer breaks the undo history  Original answer below   AFAIK there are three options  each with its disadvantages   youcompleteme  unfriendly to install  but works nice if you manage to get it working  However python3 is not supported  jedi-vim  coolest name  but breaks your undo history  python-mode does a lot more the autocomplete  folding  syntax checking  highlighting  Personally I prefer scripts that do 1 thing well  as they are easier to manage  and replace   Differently from the two other options  it uses rope instead of jedi for autocompletion   Python 3 and undo history  gundo   are a must for me  so options 1 and 2 are out

Try Jedi  There s a Vim plugin at https   github com davidhalter jedi-vim   It works just much better than anything else for Python in Vim  It even has support for renaming  goto  etc  The best part is probably that it really tries to understand your code  decorators  generators  etc  Just look at the feature list

I ran into this on my Mac using the MacPorts vim with  python   Problem was that the MacPorts vim will only bind to python 2 5 with  python  while my extensions were installed under python 2 7   Installing the extensions using pip-2 5 solved it

This can be a good option if you want python completion as well as other languages  https   github com Valloric YouCompleteMe  The python completion is jedi based same as jedi-vim

I found a good choice to be coc nvim  with the python language server   It takes a bit of effort to set up  I got frustrated with jedi-vim  because it would always freeze vim for a bit when completing   coc nvim doesn t do it because it s asyncronous  meaning that   It also gives you linting for your code  It supports many other languages and is highly configurable   The python language server uses jedi so you get the same completion as you would get from jedi
