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.
