Question

5.12 A5 Program Do you want to play. a. game? The Big Bang Theory fans may recognize Rock Paper Scissors Lizard Spock as a game of chance that expands on the standard Rock Paper Scissors game. It introduces two new hand signs and several more rules.

Answer 1

Here, I have updated the outcome function with a couple of missing cases out of the 10 rules. Rules are mentioned as comments along the code for readability.

Code:

def outcome(player1, player2):
   if player1 == choices[2] and player2 == choices[1]: # Scissor cuts Paper
       return 'win'
   elif player1 == choices[1] and player2 == choices[0]: # Paper covers Rock
       return 'win'
   elif player1 == choices[0] and player2 == choices[3]: # Rock crushes Lizard
       return 'win'
   elif player1 == choices[3] and player2 == choices[4]: # Lizard poisons Spock
       return 'win'
   elif player1 == choices[4] and player2 == choices[2]: # Spock smashes Scissors
       return 'win'
   elif player1 == choices[2] and player2 == choices[3]: # Scissors decapitates Lizard
       return 'win'
   elif player1 == choices[3] and player2 == choices[1]: # Lizard eats Paper
       return 'win'
   elif player1 == choices[1] and player2 == choices[4]: # Paper disproves Spock
       return 'win'
   elif player1 == choices[4] and player2 == choices[0]: # Spock vaporises Rock
       return 'win'
   elif player1 == choices[0] and player2 == choices[2]: # Rock crushes Scissors
       return 'win'
   elif player1 == player2:
       return 'draw'
   else:
       return 'lose'

human_player function mentioned above is mostly right with just a correction of indentation. I have shared the update code below:

def human_player():
   while True:
       choose = input("rock, paper, scissors, lizard or spock? ")
       if choose.lower() in choices:
           return choose.lower()
       else:
           print('Incorrect Selection')

I have also added a call to the main() function after seed(42) so as to play the game.

Screenshot of the entire code:

from random import choice, seed choices = ['rock', 'paper', 'scissors', 'lizard', 'spock'] def outcome (playeri, player2): if player1 == choices [2] and player2 == choices [1]: # Scissor cuts Paper return 'win! elif playeri == choices[1] and player2 == choices [O]: # Paper covers Rock return 'win! elif player1 == choices [0] and player2 == choices [3]: # Rock crushes Lizard return 'win' elif playeri == choices [3] and player2 == choices [4]: # Lizard poisons Spock return 'win! elif player1 == choices [4] and player2 == choices [2] : # Spock smashes Scissors return 'win' elif player1 == choices [2] and player2 == choices [3]: # Scissors decapitates Lizard return 'win! elif player1 == choices [3] and player2 == choices [1]: # Lizard eats Paper return 'win' elif playeri == choices[1] and player2 == choices [4]: # Paper disproves Spock return 'win! elif player1 == choices [4] and player2 == choices [O]: # Spock vaporises Rock return 'win! elif playeri == choices [0] and player2 == choices [2] : # Rock crushes Scissors return 'win! elif playeri == player2: return 'draw else: return 'lose' def human_player(): while True: choose = input("rock, paper, scissors, lizard or spock? ") if choose. lower() in choices: return choose. lower() else: print('Incorrect Selection') def computer_player(): return choice (choices)

def main(): human = human_player() computer = computer_player() print (human, outcome (human, computer), computer) if __name__ == "__main__": seed (42) main()
