row = {"fname" : "Frank", "lname" : "Jones", "city" : "Hoboken", "state" : "Alaska"} cols = ("city", "state")
Is there a best-practices way to ask for an object containing only the keys named in cols out of row? In other words, to get this: {"city" : "Hoboken", "state" : "Alaska"}
Why would you need to do that? There's nothing you can do to the second dictionary that you can't do to the first, so what's wrong with leaving the extra items in place?
