SPOP

SPOP key [count]

Available since 1.0.0.

Time complexity: O(1)

Removes and returns one or more random elements from the set value store at key.

This operation is similar to SRANDMEMBER, that returns one or more random elements from a set but does not remove it.

The count argument is available since version 3.2.

Return value

Bulk string reply: the removed element, or nil when key does not exist.
