Personally I would avoid a default because I'm unsure whether the current or
the previous month is the right default.
Also, the default month combined with a specific year doesn't make much
sense to me, and someone who specifies find_monthly_expenses(month=6) in May
probably wants the June of the past year...
Keep the function simple an make the arguments non-optional. If you can come
up with a nice heuristic put it in a separate function.
