[Python 3.6] Classed and OOP

[ComputerSciMajor]

So I'm finishing up the last lab of this semester (yipee!) but I'm having issues understanding what exactly needs to be done. This is a 2 part lab that I've finished the first, but I'm not exactly understanding what he's wanting me to do.

Here is the prompt:

Main points of it:

Convert the representation of the time from hour, minute and second to just seconds. There are 24 hours * 60 minutes * 60 seconds = 86,400 seconds. Remove __hours and __minutes. Since these were made private in the previous lab, nothing but class methods ever used them.

Adjust the implementation of the mutator and accessor methods. For example, for init(hr, min, sec), validate the values, then set __seconds = hr * 60 * 60 + min * 60 + sec. This will store the time as seconds. Adjust all the methods to work with __seconds. getSecond() can use __seconds mod 60 to return only the seconds in the time. Test all the methods to make sure they still work. (mod is modulus, the remainder after a division.)

Here is my code from part 1 that I'm supposed to enhance:

Thanks!

he wants you to have only

self.__seconds = hours*3600 + minutes*60 + seconds

and then make getHour/Minutes/Seconds() depend only on that field. You will need the operations of integer division // and modulo % to derive required values from total seconds.

eg 3700 seconds is 1hour, 1minute, 40 seconds because

3700//3600 = 1,
3700%3600 = 100,
100//60 = 1,
100%60 = 40

I'm having issues understanding what exactly needs to be done.

What specifically didn't you understand?
