In a nested fore loop, the outer fore loop is basically reads for j in range of one to the length of your list. And then right inside that fore loop, you're creating a basically variable that's the jath element of yourList. So all you're doing is skipping the very first element of your List. But the way you're doing this is generating explicit indexes based on the range function and the length function. It just seemed like the only reason they were doing all this was to skip over the first element. Once again, python has very, very many nice features. They have something called slicing, where you can basically pass it the syntax, which is square bracket, and
