The answer is neither. The second shows the intent in part but doesn't
quite get it right.
The intent is to have a string template and insert values in that template:
print("You've visited {} & {}.".format(island, new)
This is totally clear what is going to happen. I'm not relying on the
behaviour of print() to format my string. Format does the formating, print
the printing :)
This separation of concern is a basic building block of good code and is
seen at various scale levels. At a higher level, it is seen in concepts
like MVC.
Another thing you do by having your string separated, is you could have
them defined elsewhere and have, say, a version in english and a version in
french.
I;m sure you can see the value.
