You can install either IPython or bpython to provide additional interface options for Python shells, or you can install both, if you want a choice. These will highlight the syntax for the output of your Django shell, and will add some other helpers. Install them by using one of the following commands for a virtual environment, or add them to your requirements and rebuild for a Docker project:

(myproject_env)$ pip3 install ipython~=6.5.0
(myproject_env)$ pip3 install bpython~=0.17.1
