I have a nested list of lists which shows rooms and which floors are inside them. However I can’t seem to work out how to convert that list so that it only shows floors whilst preserving the indices (images below should explain more):
Yes, I reckon this should get me there provided I can use the ‘empty’ entries in the original list as a Boolean mask on the list of all rooms. That way the indices for my rooms and floors will match up. Cheers
Left the office now, will have to try it out later.
