In this post, the top answer says that
Alternatively you can go put your device in Developer Mode and gain access to a shell from where you can install/launch Python.
I want to know how to do this. Please note that I do not want to install crouton, just be able to run python in the shell. Thanks.
Update: I found the command to install python. on this article near the bottom it says to use the command.
This installs a large amount of things straight into the console, including python.
