Oh thanks a lot. Just getting started with classes xd

If there are no arguments passed, you should raise an error. (if not args: raise Error)

How do i solve "exception expected" error? (solved all random cases, Python)

I like this kata, but for me it is definetely harder than 6 kyu.

When I try to put all elements from the date to my list, the mathematical operation('/') happens before it is converted to string. Where can I read how to solve this?

You probably created a list for every possible pair of number, so it requires too much time to check it, because there are over 300 tests. You should look for another algorithm, which works faster and cleaner.
