Jedi is an autocompletion tool for Python. It works. With and without syntax errors. Sometimes it sucks, but that's normal in dynamic languages. But it sucks less than other tools. It understands almost all of the basic Python syntax elements including many builtins.

To enable this addon in your (Neo)Vim use one of these two methods: * Add "packadd! python-jedi" to your vimrc file * Invoke: `vam install python-jedi` if you use Vim Addon Manager
