Here is an updated version of the code with some modifications:
```python
import random
# given an input list of cards, shuffle them and return a new shuffled list
def shuffle(deck):
random.shuffle(deck)
return deck
# ensure the human player picks a valid spade from the remaining cards in hand
def p1_algorithm(p1_spades):
return random.choice(p1_spades)
# given the complete state of the game, this AI algorithm will make a choice
# for the computer player and return the resulting selection.
def p2_algorithm(middle_cards,diamonds,p1_spades,p2_clubs):
return random.choice(p2_clubs)
def play_round(diamonds, p1_spades, p2_clubs, p1_capture, p2_capture, middle_cards):
middle_card = diamonds.pop(0)
middle_cards.append(middle_card)
print("Middle card(s):", middle_cards)
print(" Player 1 available:", p1_spades)
player1_bid = p1_algorithm(p1_spades)
p1_spades.remove(player1_bid)
player2_bid = p2_algorithm(middle_cards,diamonds,p1_spades,p2_clubs)
p2_clubs.remove(player2_bid)
print(" Player 2 bid:", player2_bid)
if player1_bid > player2_bid:
while len(middle_cards) > 0:
value = middle_cards.pop(0)
p1_capture.append(value)
print(" Player 1 wins bid, has captured", p1_capture)
elif player2_bid > player1_bid:
while len(middle_cards) > 0:
value = middle_cards.pop(0)
p2_capture.append(value)
print(" Player 2 wins bid, has captured", p2_capture)
else:
print(" Tie bid - middle card remains")
def determine_winner(p1_capture, p2_capture):
print("===GAME OVER===")
if len(p1_capture) > len(p2_capture):
print("Player 1 wins!")
elif len(p2_capture) > len(p1_capture):
print("Player 2 wins!")
else:
print("It's a tie!")
# MAIN PROGRAM LOGIC
# NO STUDENT CHANGES BELOW THIS POINT
# randomize random number generator with a known seed for repeatability
seed = int(input("Enter random seed: "))
random.seed(seed)
# initialize 3 hands, each with cards 2 - 10
diamonds = [2,3,4,5,6,7,8,9,10]
p1_spades = [2,3,4,5,6,7,8,9,10]
p2_clubs = [2,3,4,5,6,7,8,9,10]
# initialize empty lists of cards that each player captures or that are in the middle
p1_capture = []
p2_capture = []
middle_cards = []
# shuffle the deck of diamonds
diamonds = shuffle(diamonds)
# game continues while diamonds are left
while len(diamonds) > 0:
play_round(diamonds, p1_spades, p2_clubs, p1_capture, p2_capture, middle_cards)
# all diamonds are gone, so game is over - time to determine winner
determine_winner(p1_capture, p2_capture)
```
These changes include using random.shuffle() to shuffle the deck of cards, using random.choice() for selecting player bids, and updating the determine_winner() function to correctly determine the winner based on the number of captured cards.
