Three reasons for why it's better but it doesn't actually work as given.
island = "Isle Of Wight"
new = "Isle of Wong"
print("You've visited {0} & {2}.".format(island, new))

Hi there,
In a program I wrote the following line (Python 3.5):

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

I hadn't seen that before. Interesting link, thanks.
I think I like it but only time and experience will

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
