Pull ups are not needed.so after some testing, retesting, re checking and trying to get the pin.pull_up to work I have still been getting 0's across all the d's until I jiggled the board on the bread board, where I saw 1's go on some or all of the d's which I thought was a possible step in the right direction although I didn't press any keys, only strange thing was that the 1 would flash up but seemingly roll up the others e.g. if 1 started on D0 it would progressively make it's way up the other numbers during each interval until it reached D7, I'm thinking of bypassing the bread board at the moment in favour of cutting the ends off some of the jumpers so that I can still change the end if needed, my other thought is to cut the ribbon cable and solder that to the board just in case there is something that may be causing an issue
Could you please post a photo of your test setup showing how you have connected things together?
