# LSET _key_ _index_ _value_

Time complexity: O(N) (with N being the length of the list)

> Set the list element at index (see LINDEX for information about the_index_ argument) with the new value. Out of range indexes willgenerate an error. Note that setting the first or last elements ofthe list is O(1).

> Similarly to other list commands accepting indexes, the index can be negative to access elements starting from the end of the list. So -1 is the last element, -2 is the penultimate, and so forth.
