Jedi is a static analysis tool for Python that is typically used in IDEs/editors plugins. Jedi has a focus on autocompletion and goto functionality. Other features include refactoring, code search and finding references.

Jedi has a simple API to work with. There is a reference implementation as a

_. Autocompletion in your REPL is also possible, IPython uses it natively and for the CPython REPL you can install it. Jedi is well tested and bugs should be rare.

Jedi can currently be used with the following editors/projects:

  • Vim (jedi-vim, YouCompleteMe, deoplete-jedi, completor.vim)
  • Visual Studio Code
    _ (via
    Python Extension 
  • Emacs (Jedi.el, company-mode, elpy, anaconda-mode, ycmd_)
  • Sublime Text (SublimeJEDI_ [ST2 + ST3], anaconda_ [only ST3])
  • TextMate_ (Not sure if it's actually working)
  • Kate_ version 4.13+ supports it natively, you have to enable it, though. [
  • Atom_ (autocomplete-python-jedi_)
  • GNOME Builder
    _ (with support for GObject Introspection)
  • Gedit (gedi_)
  • wdb_ - Web Debugger
  • Eric IDE
    _ (Available as a plugin)
  • IPython 6.0.0+ 
  • xonsh shell 
    _ has
    jedi extension 

and many more!

There are a few language servers that use Jedi:

  • jedi-language-server 
  • python-language-server 
  • anakin-language-server

Features and Limitations

Jedi's features are listed here:


You can run Jedi on Python 3.6+ but it should also understand code that is older than those versions. Additionally you should be able to use

_ very well.

Tips on how to use Jedi efficiently can be found



You can find a comprehensive documentation for the

API here 

Autocompletion / Goto / Documentation

There are the following commands:

  • jedi.Script.goto
  • jedi.Script.infer
  • jedi.Script.complete
  • jedi.Script.get_references
  • jedi.Script.get_signatures
  • jedi.Script.get_context

The returned objects are very powerful and are really all you might need.

Autocompletion in your REPL (IPython, etc.)

Jedi is a dependency of IPython. Autocompletion in IPython with Jedi is therefore possible without additional configuration.

Here is an

example video 
_ how REPL completion can look like. For the
shell you can enable tab completion in a

Static Analysis

For a lot of forms of static analysis, you can try to use

. It will return a list of names that you can then filter and work with. There is also a way to list the syntax errors in a file:


Jedi supports the following refactorings:

  • jedi.Script.inline
  • jedi.Script.rename
  • jedi.Script.extract_function
  • jedi.Script.extract_variable

Code Search

There is support for module search with
, and project search for
. The way to search is either by providing a name like
or by using dotted syntax like
. Additionally you can provide the API type like
. There are also the functions


There's a pretty good and extensive

development documentation


The test suite uses

pip install pytest

If you want to test only a specific Python version (e.g. Python 3.8), it is as easy as::

python3.8 -m pytest
