Or you could turn it into a function and "return". Or if you feel like
it, you could turn the nested loops into a generator, then iterate
over it and break when you need to. There are many things you CAN do,
but to the true goto-aficionado, none of them is as clean.
Personally, I can't remember the last time I yearned for "goto" in
Python, and the only times I've ever wished for it or used it in other
languages have been multi-loop breaks or "for...else" blocks. And
neither is very frequent.
