I on python,my answer is working but I don't understand why a for loop I have runs twice the same thing with any other loop I try, it for some reason just keep running twice and because of that it gives me the wrong answer. also when I try to run test cases there aren't any.

really interesting and a lot can be learned on this by beginners like me

When trying out test cases in python it gives an error even when the code works

I keep getting this error "TypeError: () takes exactly 1 argument (5 given)" and I don't know what's wrong, it seems to work for the test cases and when I submit it worked and still gives this error and says 2 passed what am I doing wrong?

I need some help, it keep's saying that I have too many wires defines but I made sure that I only have 10 wires, any help? Also sometimes it also says init takes 2 arguments and only one is given? What am I meant to do?

I have the code working but it just won't accept it. It keeps saying 'set([1])' should equal set([1])' what do I do?
