Be aware, though, that if you're doing *lots* of this (like, for instance,
adding numerous strings inside a tight loop or something), a is much less
efficient. Each time you add a string, the interpreter creates a new string
object and copies the contents of the existing strings there. In this
particular example, that's three temporary string objects, but if you're
building up a long string out of numerous variables, it could be a *lot*
more. On the other hand, method b will only create a single string object, no
matter how many different variables you insert. Also, b will let you do a lot
more specific alignment, formatting of numbers, etc. There's really nothing
to recommend a as being better than b, either, so learn those string
formatting codes! :)
