"In this tutorial weâ€™re going to look at
formatting strings. In the previous tute we constructed a string by
adding (using the â€˜+â€™
operator) them together. Building strings this way can be a little
challenging. Another way to do it, is to use formatting strings. We
put place markers into a string, and match the place markers with
values to go in there. The place markers are identfied by a % sign
in the string, and values are added at the end after a % sign.
