How much information about the python language should I have before programming a developmental board such as raspberry pi!
I'm just a begginer
Python is available on the raspberry pie OS, so anything you could program on another platform can be done on the raspberry pie too. So basically just the basics should suffice. To program use of external components such as LEDs or buzzers, learn how to do so here. https://www.raspberrypi.org/learning/physical-computing-with-python/worksheet
use the Rpi to learn python ;)
