For example [None:None] would make an entire copy. This is useful when you have to specify the end from the vary using a variable and want to incorporate the last product.
In that case, the lower sure is -1 which means we slice every one of the way as much as and such as the beginning, and the upper certain would be the size minus one, indicating we begin at the top. (Note that the semantics of the -one is different
