I believe there might be an issue with vote_outcome(), def vote_outcome(self, mission, proposer, votes): ''' mission is a list of agents to be sent on a mission. The agents on the mission are distinct and indexed between 0 and number_of_players. proposer is an int between 0 and number_of_players and is the index of the player who proposed the mission. votes is a dictionary mapping player indexes to Booleans (True if they voted for the mission, False otherwise). No return value is required or expected. ''' Here it says votes is a dictionary, however this is not true, it appears that it is just a list with the playernumbers who voted yes. Is it ok to consider it as a list?
