LRANGE

Returns the specified elements of the list stored at key. The offsets start and stop are zero-based indexes, with 0 being the first element of the list (the head of the list), 1 being the next element, and so on. Negative indexes can be used to denote elements starting from the tail of the list, with -1 being the last element, -2 being the second last element, and so on.

Syntax​

LRANGE key start stop

Details​

  • Available since: 1.0.0
  • Time complexity: O(S+N) where S is the distance of start from the head and N is the number of elements to be returned.
  • ACL categories: @read, @list, @fast

Example​

Assume we have a list called mylist with elements "a", "b", "c", "d", "e", and "f":

RPUSH mylist "a"
RPUSH mylist "b"
RPUSH mylist "c"
RPUSH mylist "d"
RPUSH mylist "e"
RPUSH mylist "f"

Now, let's retrieve elements from index 1 to 3 (inclusive) from mylist:

LRANGE mylist 1 3

This will output:

1) "b"
2) "c"
3) "d"
