Why is 1 % 2 = 1? I understand that 13 % 4 = 1 because 1 is the remainder of 13 / 4, but I don't see how the first modulus works. Can someone explain this please?

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".
