Side Question: when should one use __dict__ vs vars() vs getattr() ??? all three work in this case, but I'm never quite sure which is prefered, and why.
`vars(obj)` is defined as returning `obj.__dict__` so technically it probably doesn't matter, but I feel that as a matter of aesthetics and future-proofing, we should avoid direct use of dunders whenever practical. Do you prefer to write `mylist.__len__()` over `len(mylist)`? Then you will probably prefer `obj.__dict__` over `vars(obj)` too :-) -- Steve
