It'd not be as Pythonic if this were an API, but since you just
converted this from JSON, you can be fairly confident of what the data
types are. You're dealing with your program's input, and that input
can come in a specific number of forms; so you cope with each form.
This is a perfectly acceptable and reasonable way to write code.
