OBVIOUS???

The only algorithm obvious to me came to two lines and about 300
characters with all the pruning I could come up with. Changing algorithms
made it longer. I am finding it hard enough to credit that half a dozen
people are claiming lengths of around 130-180 characters -- 39 or 53 bytes
just seems physically impossible to me, especially given that nine of
those bytes are the name of the function!

The identity function seven_seg=lambda s:s takes 20 bytes and does
nothing. That leaves NINETEEN bytes to implement the functionality. In the
immortal words of Bill and Ted: "No way dude!"

You excellent dudes are righteously bodacious!
