Raspberry Pi Code Editor All In One

Code Editor is in beta
What does beta mean?
Beta means that we are not quite finished yet, and some things might not look or work as well as we’d like. However, it also means you are one of the first people to use our new Code Editor!
What next?
We'll soon be asking for your feedback, so we can work on making it better for you, and other digital makers.
GPIO module bug
ImportError: No module named RPi on line 4 of main.py
