LINDEX

Syntax
LINDEX key index
Available since:
1.0.0
Time complexity:
O(N) where N is the number of elements to traverse to get to the element at index. This makes asking for the first or the last element of the list O(1).
ACL categories:
@read, @list, @slow,

Returns the element at index index in the list stored at key. The index is zero-based, so 0 means the first element, 1 the second element and so on. Negative indices can be used to designate elements starting at the tail of the list. Here, -1 means the last element, -2 means the penultimate and so forth.

When the value at key is not a list, an error is returned.

Return

Bulk string reply: the requested element, or nil when index is out of range.

Examples

LPUSH mylist "World" LPUSH mylist "Hello" LINDEX mylist 0 LINDEX mylist -1 LINDEX mylist 3
