@championswimmer @the-dagger please have a look. About the code climate tests they are really inconsistent, the first kind of error regarding similar code are not correct, the codes are very different, and that to from the code that i didn't even change. The other errors are regarding the order of import statements which i changed thrice but each time it gives an error and tells a new order.
