correct way to create boiler plate code

[dmerrio]

Thanks for the formatting tips. Copy and pasting kind of messed up
the formatting, not that it was good to start with. I am still
developing a coding style.

> Mine is not an answer that directly helps you solve your
problem. Experience shows that messy code doesn't help you see
your problems, and sometimes it even hides bugs. So I suggest you
to reformat your code in a more human way, use more normal naming
conventions, and use named imports if you want to import just some
names.

newlines where they are belong, and so on. This helps a lot.
