The following list can be found on he calculator by starting the Python app and choosing the CMDS item in the bottom menu.
The Prime implements a subset of micropython whose full documentation is found at the Micropython site. Be aware that there are more routines documented there than exist in the Prime. For easier searching while writing code, the list below might be convenient. It is presented alphabetically, unlike on the Prime menus. Hopefully, HP will provide thorough documentation eventually.
