Just FYI, it'll become more evident when and why functions are useful as you progress to larger projects. I was a bit confused by their use when I first started too, when your entire program is only 20-50 lines of code which follows a very linear path, they don't make much sense. But when you start re-using tidbits of code, it makes sense to throw it in functions. Also makes it easier to read and follow the logic of your program if you only have to read descriptive function names, rather than deciphering what the next 5 lines of code are supposed to do.
