The programme works in the terminal but when I try to run it automatically the boot won't load the programme past the second line in the main while loop. addstar = input() giving the EOFError:when reading a line
The input is from a usb NFC tag reader which acts like a keyboard. The programme depends on the tag value.
A 'words of one syllable advice would be so appreciated'

I hadn't imported sys. I have now and it works. The programme runs perfectly on boot up.
