Description:
 def srandmember(self, key, count=None):
 """When called with just the key argument, return a random element from the set value stored at key. Starting from Redis version 2.6, when called with the additional count argument, return an array of count distinct elements if count is positive. If called with a negative count the behavior changes and the command is allowed to return the same element multiple times. In this case the number of returned elements is the absolute value of the specified count. When called with just the key argument, the operation is similar to :meth:`~tredis.RedisClient.spop`, however while :meth:`~tredis.RedisClient.spop` also removes the randomly selected element from the set, :meth:`~tredis.RedisClient.srandmember` will just return a random element without altering the original set in any way. .. 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` """
