Help for a newbie regarding code & physical switches

[Howard Spink]

Thanks for your help. I want the python to run automatically after boot and show a blank white screen, when a combination of GP10 inputs are HIGH python displays one of 150 JPEGS. Is this possible? what sort of boot times can I get with Arch?
