Description:
 def spop(self, key, count=None):
 """Removes and returns one or more random elements from the set value store at key. This operation is similar to :meth:`~tredis.RedisClient.srandmember`, that returns one or more random elements from a set but does not remove it. The count argument will be available in a later version and is not available in 2.6, 2.8, 3.0 Redis 3.2 will be the first version where an optional count argument can be passed to :meth:`~tredis.RedisClient.spop` in order to retrieve multiple elements in a single call. The implementation is already available in the unstable branch. .. note:: **Time complexity**: Without the count argument ``O(1)``, otherwise ``O(N)`` where ``N`` is the absolute value of the passed count. :param key: The key to get one or more random members from :type key: :class:`str`, :class:`bytes` :param int count: The number of members to return :rtype: bytes, list :raises: :exc:`~tredis.exceptions.RedisError` """
