Examples of redis.clients.jedis.Jedis.lindex()

redis.clients.jedis.Jedis.lindex()
Return the specified element of the list stored at the specified key. 0 is the first element, 1 the second and so on. Negative indexes are supported, for example -1 is the last element, -2 the penultimate and so on.
If the value stored at key is not of list type an error is returned. If the index is out of range a 'nil' reply is returned.
Note that even if the average time complexity is O(n) asking for the first or the last element of the list is O(1).
Time complexity: O(n) (with n being the length of the list) @param key @param index @return Bulk reply, specifically the requested element
