def create_player_sessions(GameSessionId=None, PlayerIds=None,
    PlayerDataMap=None):
    """
    Adds a group of players to a game session. This action is useful with a team matching feature. Before players can be added, a game session must have an ACTIVE status, have a creation policy of ALLOW_ALL , and have an open player slot. To add a single player to a game session, use  CreatePlayerSession .
    To create player sessions, specify a game session ID, a list of player IDs, and optionally a set of player data strings. If successful, the players are added to the game session and a set of new  PlayerSession objects is returned. Player sessions cannot be updated.
