UML is a bunch of conventions for drawing pictures which illustrate your
design.

Nothing like any of that.  It's like the stencils they sell in drafting
shops.

I've never seen the first, but I tried to learn from the second and HATED
it.  The author seems to delight in using bullet lists as part of every
paragraph, and new terms complete with definition (sometimes) are brought
in on every page.  I was _really_ disappointed.

If you already know UML, there's a possibility that it would work for you.
If you don't, there's very little chance.

UML simply helps you lay out your design on paper.

I don't have any other recommendations.

No, but ObjectDomain (which I hadn't seen before) uses UML to help
structure your program.  I'll have to check it out.

Python runs on more OSes.  Python even runs on Java.

Java isn't that nice of a language -- all you can say is that it's better
than C++.
