And it's also a way of playing around with processes. For example, we can
try to simulate something interesting like: what happens during the
"telephone" game? Can we write a program that will "simulate" the sort of
mistakes that could happen when rumors spread? Programming is a playpen
that lets us test out how things "might" work. It doesn't always have to

I think it's perfectly ok to go on first instinct on a program, and
gradually get things to look nicer. At least, when I'm learning
something, I want to try writing small procedures, and gradually get a
better understanding of a problem as I play with it. I guess you
could call it "bottom-up" programming.
On the other hand, it's good to plan for the future by try writing
programs that that are easy to fix.

At least when learning a language, though, reinventing the wheel is
important. It exercises our creative juices, and it's a good experience
to try figuring alternative ways of doing things. Not that working with
what's already written isn't a good thing --- it's wonderful to be able to
reuse code! But it's also nice to rework solutions to old problems, and
gain a better understanding of what's going inside too.
I'm sorry; I'm just looking at programming from a hobbyist's perspective.
But why program Python if it's not going to be fun?
