why is 'senior' still outputted in this case? I understand that '42' and 'default' outputs because the criteria matches and there is no break, but 'senior' is still false is it not?

I really do not understand the "property" and the "setter". The "property" makes the attribute read-only, but the "setter" makes the attribute mutable. So if we want to use "property", why we need to introduce the "setter".

I don't understand this 'return' stuff. where exactly does it return to?. For instance, if I type 'return 0' or 'return 1' or 'return sum', what is the difference?. Where does 0,1,sum return to (or what does it return?) and what is the reason for the return?
