Slice syntax for python 2.7, reverse a part of a list

Question

How do I use the slice syntax of python to get a list from 0 to i in reversed order?

For example, if the list is [1, 2, 3, 4] and i == 2, the result should be [3 ,2 ,1].

What, if anything, have you tried so far? – jonrsharpe May 04 '14 at 19:56 — jonrsharpe, May 04 '14 at 19:56

The 2 is the first character instead of the second because it takes effect after the reversal (you take steps backwards)

>>> [1,2,3,4][2::-1]
[3, 2, 1]
