refactor, reduce nesting

not sure if my python is 100% correct, its syntactically correct according to the interpreter, but had an problem withs some dependencies
I'm not really sure where the typo is.

Also dunno if they should or shouldn't be a method on the object.

Although it is much easier to test as a method on the object.
