still kinda new to this site (sorry if i messed up) so my homework for the week is working with lists... my professor wants me to modify my rock, paper, Scissors game to use a 2d list. which i was able to make. the rest is the problem. i need to search the 2d list for the outcome, and post if the player won or the computer, and keep track of the number of wins each has, until the player doesn't want to play anymore. i've looked and tried two different ways to do a search but i either end up in an endless loop or it ends without doing anything... right now i'm stuck with an endless loop. the output is easy part i think.
This is my current code after doing multiple re-writes... i have everything else from the old version that doesn't use a list commented out so i didn't post it.
compchoice = " "
humwin = 0
compwin = 0
again = 'Y'
playing = True
outcomes = [[1, 2], [2, 3], [3, 1], [2, 1], [3, 2], [1, 3], [1, 1], [2, 2], [3, 3]]
#thelist = []
#thelist.append("Player 1 = {playerchoice}, Player 2 = {compchoice}")
while playing:
playerpic = int(input("Pick 1 for Rock, 2 for Paper, or 3 for Scissors: "))
comppic = random.randint(1, 3)
pick = [playerpic, comppic]
for x in range(len(outcomes)):
for i in range(len(outcomes[x])):
if pick == outcomes[x][i]:
print("You chose Rock.")
print("Computer choose Paper")
print("You lost")
compwin += 1
print("Human: ", humwin, " Computer: ", compwin)
break
#will not break, seems to ignore if? missing something!
Basically, you have all the possible combinations that the player and computer can choose. It just appears that these choices need to be categorized into the ones where the computer is the winner, the ones where the player is the winner, and the ones that are ties. Also, it appeared that there needed to be an added bit to prompt the user as to when the game would conclude. With those additional bits, following is one possible refactored version of the code.
import random
compchoice = " "
humwin = 0
compwin = 0
again = 'Y'
playing = True
choice = ['Rock', 'Paper', 'Scissors']
outcomes = [[1, 2], [2, 3], [3, 1], [2, 1], [3, 2], [1, 3], [1, 1], [2, 2], [3, 3]]
#thelist = []
#thelist.append("Player 1 = {playerchoice}, Player 2 = {compchoice}")
while playing:
playerpic = int(input("Pick 1 for Rock, 2 for Paper, or 3 for Scissors: "))
comppic = random.randint(1, 3)
pick = [playerpic, comppic]
for x in range(len(outcomes)):
if pick == outcomes[x]:
print("You chose", choice[playerpic - 1])
print("Computer choose", choice[comppic - 1])
if (x < 3): # In those choice combos, the computer wins
print("You lost")
compwin += 1
elif (x < 6): # In choices 4 - 6, the player wins
print("You won")
humwin += 1
else: # The last three combos are a tie
print("Tie")
print("Human: ", humwin, " Computer: ", compwin) # List the current score
cont = input("Play again Y/N ") # Need to ask a question to continue playing
if (cont != 'Y'):
break
The things to note:
Testing out this refactored code, following is some sample terminal output.
craig@Vera:~/Python_Programs/Games$ python3 RockPaperScissors.py
Pick 1 for Rock, 2 for Paper, or 3 for Scissors: 1
You chose Rock
Computer choose Scissors
You won
Human: 1 Computer: 0
Play again Y/N Y
Pick 1 for Rock, 2 for Paper, or 3 for Scissors: 1
You chose Rock
Computer choose Rock
Tie
Human: 1 Computer: 0
Play again Y/N Y
Pick 1 for Rock, 2 for Paper, or 3 for Scissors: 3
You chose Scissors
Computer choose Rock
You lost
Human: 1 Computer: 1
Play again Y/N N
Go ahead and dissect this and hopefully get a better understanding of lists and tests.
