Python on the TI-84 series is run on a separate ARM Cortex-M0+ micro-controller with 256 KiB of Flash and 32 KiB of RAM, hooked to the ASIC with what appears to be a UART. In other words, it's just about the worst performing Python implementation in a graphical calculator to date: https://www.cemetech.net/forum/viewtopic.php?p=285853#285853 (alongside a rant about removal of C/ASM support, some points about it being outdated).
