items = [town, apple, car, phone]
values = [7, 5, 2, 1]

Hi Diez,
Thanks for this, I had seen zip() before but had no idea
really what it does, this will serve as good motivation to
find out more.
I'm amazed at what this language can do (and the helpfulness
of the people on the list here).
Best,

items = [apple, car, town, phone]
values = [5, 2, 7, 1]
