Regardless, it clearly isn't doing what you want. In this situation it
is helpful (to us, and therefore to you later) to post the output from a
run and an example of the output you wanted, and and description of what
is deficient in the programme output. You've got the last 2 of these 3.

Well, you only make one pass over the list. So if emptyList[0] <=
emptyList[1] _on the first (and only) pass_, it will not move.

Try comparing:

2 5 3

and:

3 2 5

and see if the behaviour differs.

BTW, what you['re implementing looks like a bubble sort to me (look it
up). But a since pass over the list isn't enough to sort the whole
thing.
