Texas Instruments announced that they are adding a new graphing calculator called TI-84 Plus CE Python. The TI-84 Plus uses CircuitPython rather than the standard Python that most developers are aware of.
CircuitPython is made by AdaFruit for embedded devices, like a calculator. You can read more about CircuitPython being added to the calculator over on AdaFruit’s website.
CASIO also has a graphing calculator that includes a version of Python called the fx-CG50 PRIZM calculator. It uses MicroPython, which is what CircuitPython is based on.
Hopefully, Hewlett-Packard (HP) will see the light and add Python support to one or more of their graphing calculators as well. Time will tell.
