I am getting the Elegoo Super Starter Kit (Arduino Uno R3) to tinker
with (it's on order as of when I'm writing this post).
I looked in the Debian repos for stuff on Arduino and didn't find much
(at least not of interest to me).
I did download the IDE from Elegoo and their tutorials and libraries.
But it's all in C/C++. While I do know C and C++ (to some extent), I'm
very bad at it (I admit to not using it very much, maybe once every
other blue moon and lately we haven't had any blue moons that
warranted using C).
I recently been doing stuff in Python (especially for work, which is
not Arduino related in any way). I am really getting to like Python. I
have created my own Python Libraries for other things (again
unrelated) and even compiled them to .so (binary) using the 'cython'
compiler.
While I could create C source of a Python script using cython, I don't
know how to compile the resulting C source and upload it to the
Arduino board. I would like to use gcc.
Is there a cross-platform compiler for Arduino and gcc that anyone has
had experience with that works or they can recommend?
Or some way to program in Python?
I'll use C/C++ until I can figure the Python stuff out. But I really
would like to be able to use Python at some point.
It sounds like your intended use is as a hobbyist (?).
Yes. I heard about it and got curious. I liked tinkering with
electronics back in the day and kinda wondered what this is about. It's
just basically for my own fun. I don't expect to make something the
world can't live without or anything like that.
STFW for Arduino Uno R3: >

Microcontroller ATmega328P
Flash Memory 32 KB (ATmega328P) of which 0.5 KB used by bootloader
SRAM 2 KB (ATmega328P)
EEPROM 1 KB (ATmega328P)
Clock Speed 16 MHz
STFW for the CPU:

The Atmel® picoPower® ATmega328/P is a low-power CMOS 8-bit
microcontroller based on the AVR® enhanced RISC architecture.
STFW for embedded Python:
https://www.usenix.org/system/files/conference/atc12/atc12-final30.pdf
This paper presents one mechanism for doing so:
an efficient embedded Python run-time system named
Owl. The Owl system is a complete Python development
toolchain and run-time system for microcontrollers that
do not have enough resources to run a real operating sys-
tem, but are still capable of running sophisticated soft-
ware systems. These microcontrollers typically operate
at 50–100 MHz, have 64–128 KB of SRAM, and have
up to 512 KB of on-chip flash.
Note that the frequency, RAM, and ROM requirements for embedded Python
exceed what is provided by the Arduino Uno. So, that explains why I
also find no solutions for Python on the Arduino Uno R3.
If you want an embedded kit that can do Python (2 or 3?), your best bet
is to get a kit that supports Python OOTB:
https://wiki.python.org/moin/EmbeddedPython
Getting a kit that supports Linux OOTB would give you even more options:

Lots of info there. Well, glad it's possible. Looks like it'll take some
doing though. Obviously there won't be anything in Debian's Repo for it
like I hoped.
Thank you for giving me some ideas on what to look for. That'll keep me
busy for awhile!
