Consider that format has to build the entire output as a new string in
advance:
"You've visited {0} & {2}.".format(island, new)
gets generated before being passed to print for

That argument doesn't make sense to me. I think you

And as Chris points out, if there is any possibility that the words will be
in a different order in a different language, use {0}, {1} instead of {}.

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

Hi there,
In a program I wrote the following line (Python 3.5):
print("You've visited", island, '&', new + ".")
A programmer told me that it's a bad habit, and I should have used instead:
print("You've visited {0} {1} {2}{3}".format(island, "&", new, "."))
