"""
To use Jedi completion in Python interpreter, add the following in your shell
setup (e.g., ``.bashrc``). This works only on Linux/Mac, because readline is
not available on Windows. If you still want Jedi autocompletion in your REPL,
just use IPython instead::

    export PYTHONSTARTUP="$(python -m jedi repl)"

Then you will be able to use Jedi completer in your Python interpreter::

    $ python
    Python 3.9.2+ (default, Jul 20 2020, 22:15:08)
    [GCC 4.6.1] on linux2
    Type "help", "copyright", "credits" or "license" for more information.
    >>> import os
    >>> os.path.join('a', 'b').split().in<TAB>            # doctest: +SKIP
    ..dex   ..sert
