Question

please answer "class playerexception(exception):" in python

Notes Two players will face each other. They each decide independently to "cooperate" or "cheat". If they both cooperated, they each win two points. If they both cheated, nobody wins anything. one cheats, the cheater gets +3 and the cooperator loses a point. That wasn't very kind! One turn is defined as each player making a choice, and winning or losing some points as a result. Shared history against this player is available to players, and they may use this to guide their decision. It costs one point to play a turn. A player's points may go negative, and yet they can still spend/lose more points. One game is defined as two players playing multiple turns together. Their increasingly shared history will certainly affect their chosen behavior: will they keep cooperating even if their opponent doesn't? Will they hold grudges? Between games, players will reset their history, perhaps this new person is more trustworthy! A tournament involves multiple players. Each round, all players play each other once, accumulating or losing points. At the end of the round, some lowest scorers are removed (and any others with negative points), and some highest scorers are duplicated. After all rounds have been played, we see the "evolved" population of who remains, as a summary dictionary of the count of each style of player that survived. Kinds of Players There are five kinds of players in our version of the tournament. (they have unique first letters too...) • previous starts by cooperating, then always copies the previous move of their opponent. (this was the "copycat" in the shared link). • friend always cooperates, no matter what. May be vulnerable to abuse! (this was the "cooperator" in the shared link). • cheater never cooperates. (this was the "cheater" in the shared link). • grudger cooperates as long as the opponent does, but after one non-cooperation, never cooperates ever again with this opponent. (this was the "grudger" in the shared link) • detective starts with cooperate, cheat, cooperate, cooperate; then if they've never been betrayed, they cheat. If ever they are betrayed, they behave like previous does. (this was the "detective" in the shared link)
