I'd guess 99+% of Arduino projects use the C/C++ thing the Arduino IDE uses.

Micro Python and Circuit Python will run on a lot of the same boards Arduino IDE works with, but it's a much much smaller scene then Arduino/C++ I think.

You are probably right. I have a lot of raspberry Pi Pico, which I've been programming with Python, and so that just carries over when I tool around with Arduino. From that direction, it is easy to assume Python is the more popular one.

C/C++ should probably outperform Python. Either way, op should feel at home, since they listed both languages.

Right. I can see that. I've got half a dozen Picos on my coffee table that I've yet to do anything with. Mostly a drunk covid lockdown impulse buy for me...
