The sorted_lst[0:5] notation is called a slice, and returns the first 5=20
elements in the list.Read it as "from and including 0 until but not=20
including 5." It only returns 5 elements.

While this seems intuitive at first glance, you will get to like this as=20
you program more. It simply fits most problems better than it would if=20
it included the last element. (You would have "1 off" errors constantly=20
in your code)
