The manual says the editor can only handle files with up to 150 lines, though it can execute files larger than that. This is kind of annoying but not a dealbreaker. The latest OS update adds the casioplot module so you can use graphics from Python. I also read that the calculator uses the same processor as the Prizm, so it runs at 58MHz instead of 29MHz like the g and gii models. The spreadsheet mode and e-activity mode, which seems to be like a Jupyter notebook, are also really neat. They probably aren't news to most people but this is the first new Casio I've gotten since the AFX 2.0+ Smile

One thing I have not figured out is how to open a text file from Python. The "open" command is supported but returns "NoneType" since I'm probably missing the path for the file I'm trying to open. Anyone know how to do it?

Another thing that would be interesting is inlining assembly, which MicroPython supports with a decorator: 10. Inline assembler. The calculator recognizes @micropython as a decorator, but I couldn't get it to recognize .asm or .asm_sh4. With a limit of 150 lines, you couldn't write much assembly, but it might be enough to jump into a library written in C and designed to be called from Python.


This posts makes me confused. I bought a FX9860GIII one month ago and there is no "casioplot" module installed for the built-in uPython, and no OS update from CASIO.

Also, does the FX9860GIII use the same SDK released for the FX9860GII?

Your fx-9860GIII is probably preloaded with OS version 3.21.
Just update to latest version 3.40 (2020 November 25th) in order to get the casioplot module in Python :
