Question

please answer "def turn_payouts(move_a, move_b):" 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)

Hello,

def turn_payouts(move_a, move_b) function in python for this program will actually returns the point gain by both player after both player play a turn.

It will return tuple of 2 integer for each player point after checking their moves. Moves are provide in parameter move_a, move_b for player A and player B respectively.

Function may be declare as follows:

def turn_payouts(move_a, move_b):
# point_a for Player A, point_b for Player B
point_a = 0
point_b = 0
# check if move_a is cooperate
if move_a == 'cooperate':
# check both move is cooperate then both point is 2
# else Player A point will 0, player B point will 3
if move_b == 'cooperate':
point_a = 2
point_b = 2
else:
point_a = 0
point_b = 3
  
# move_a is cheater. Now check move for Player B
# If move_b is cooperate then point_a will be 3, point_b will be 0
# else both players point will be zero
else:
if move_b == 'cooperate':
point_a = 3
point_b = 0
else:
point_a = 0
point_b = 0
  
# return tuple of both player's point in tuple.   
return (point_a, point_b)

def turn_payouts (move_a, move_b): # point_a for player A, point_b for Player B point_a = 0 point_b = 0 # check if move_a is cooperate if move_a == 'cooperate': # check both move is cooperate then both point is 2 # else Player A point will o, player B point will 3 if move_b == 'cooperate': point_a = 2 point_b = 2 else: point_a = 0 point_b = 3 # move a is cheater. Now check move for Player B # If move_b is cooperate then point_a will be 3, point_b will be o # else both players point will be zero else: if move_b == 'cooperate': point_a = 3 point_b = 0 else: point a = 0 point b = 0 # return tuple of both player's point in tuple. return (point_a, point_b)

This function is used by another function like:
points = turn_payouts('cooperate','cheater')

# points will now equal to (0,3)
