My goal was trying to keep score for player and computer. If the user wins, they get a point. If the computer wins, they get a point. If its a tie, neither of them gets a point.
The following code shows you three rounds of three games of a simulated user input game with its result. It is your code only slightly changed to count properly the results:
import random
lst_user_input = [
"list faking user input:"
,"scissors"
,"paper"
,"rock"
,"y"
,"scissors"
,"paper"
,"rock"
,"y"
,"scissors"
,"paper"
,"rock"
,"n"
]
options = ("rock", "paper", "scissors") # three options
running = True
computer_score = 0
player_score = 0
round_no = 0
while running: # continuing the game
#player = "" # storing the player's choices
round_no += 1
computer = random.choice(options) # computer will choose a random choice from the options
#while player not in options: # the player has to choose one of the options, if not, it will still keep on looping
# player = input("Enter a choice (rock, paper, scissors): ")
print(round_no)
player = lst_user_input[round_no]
print("Player : " + player) # player(user) vs. computer
print("Computer: " + computer)
if player == computer:
print("It's a tie!")
elif player == "rock" and computer == "scissors":
player_score += 1
print("You win!")
elif player == "paper" and computer == "rock":
player_score += 1
print("You win!")
elif player == "scissors" and computer == "paper":
player_score += 1
print("You win!")
else:
computer_score += 1
print("You lose!")
print("Player score:", player_score)
print("Computer score:", computer_score)
if not round_no % 3: # ask only each 3 rounds
#play_again = input("Play next 3-rounds? (y/n): ").lower()
round_no +=1
play_again = lst_user_input[round_no]
if play_again == "y":
running = True
print("Yes sir!")
else:
running = False
print("Thanks for playing! ")
Here an example of printed output:
1
Player : scissors
Computer: paper
You win!
Player score: 1
Computer score: 0
2
Player : paper
Computer: scissors
You lose!
Player score: 1
Computer score: 1
3
Player : rock
Computer: paper
You lose!
Player score: 1
Computer score: 2
Yes sir!
5
Player : scissors
Computer: paper
You win!
Player score: 2
Computer score: 2
6
Player : paper
Computer: rock
You win!
Player score: 3
Computer score: 2
Thanks for playing!

For my exercise, I have to get the computer to play against the user in RPS. However, after both the computer and I input our action, the user will always receive a 'You Lose'.
import random
def get_computer_move():
"""Deterministic 'random' move chooser"""
options = ['rock', 'paper', 'scissors']
return options[random.randint(0, 2)]
def game_result(move1, move2):
"""game_result *exactly* as defined in question one"""
options = ["rock", "paper", "scissors"]
if move1 == move2:
return 0
elif move1 == "paper" and move2 == "rock":
return 1
elif move1 == "rock" and move2 == "scissors":
return 1
elif move1 == "scissors" and move2 == "paper":
return 1
else:
return 2
def main():
"""Runs a single game of PSR"""
print("Let's Play Paper, Scissors, Rock!")
user1 = input("Player one move: ").lower()
computer1 = print("The computer plays " + get_computer_move())
game_result(computer1, user1)
if user1 == computer1:
return print("It's a draw")
elif user1 == "paper" and computer1 == "rock":
return print("You win")
elif user1 == "rock" and computer1 == "scissors":
return print("You win")
elif user1 == "scissors" and computer1 == "paper":
return print("You win")
else:
return print("You lose")
main()
Here is my code although it is quite messy.
What I want to happen is:
Let's Play Paper, Scissors, Rock!
Player one move: ROCK
The computer plays rock
It's a draw
But it will always come out as:
Let's Play Paper, Scissors, Rock!
Player one move: ROCK
The computer plays rock
You lose
Help would be appreciated.
print returns none, you want to save the computers move and then print that separately
computer1 = get_computer_move()
print("The computer plays", computer1)
The Python program generates rock, paper, scissors game. The game works; however, I am having trouble keeping up with the score. I use the count method to calculate the amount times the user wins, cpu wins, # of rocks/paper/scissors that have been used.
I looked at other similar questions similar to mine. I am stuck because I am using functions. I want to keep the function format for practice.
I tried setting the counter to equal to 0's as globals. That gave a lot of traceback errors.
I tried changing the while loop within the game() function, but that produced an infinite loop. I kept the while loop within the main() function.
What is the best way to approach this? I want to be able to keep scores and for the count to update until the user quits the program.
Thank you!

What you call game is only a round. So you have to put the while loop inside the game function.

In order to keep your current flow (where game only runs one round), you have to preserve the stats in-between rounds.
This can be done caching stats in a dictionary an returning as follows.
Code
import sys
import random
def get_user_input():
print("\nWhat do you choose to play? (r, p, s) or q to QUIT ")
player = input().lower()
if player == 'r':
print("You chose: ROCK")
return player
elif player == 'p':
print("You chose: PAPER")
return player
elif player == "s":
print(" You chose: SCISSORS")
return player
elif player == "q":
sys.exit(0)
else:
sys.exit(0)
def game(player, stats = None):

# Retrieve stat values
rounds = stats['rounds']
user_wins = stats['user_wins']
computer_wins = stats['computer_wins']
tie_count = stats['tie_count']
rocks = stats['rocks']

You have set the values to 0 within the function so every time the function will be called, the rounds will be set to 0. Try initializing the variable outside the function. That should fix it.
I am new to python and as a practice I'm trying to write a rock paper scissors with it.
I triple checked eth but i can't find the problem.
I'm using visual studio code console. the msvcrt is for "getch" and I'm not sure about about the random function syntax
problem: when you give it the input number, It doesn't do or write anything despite the program.
help me pleaaaaase.

Well, the reason your code doesn't work is because you are not assigning the return value of your functions to any variable. To fix your code you need to do the following:
sm = rand(sm)
pm = playermove(pm)
In Python, passing an immutable object like string means that you cannot make any changes to it. As you're not using the passed value, your function's signature should actually look like this.
def rand()
def playermove()
After you do this, you'll see there are other things you need to fix in your code.
Try this code. Just replace snake, water, gun by rock, paper, scissors.
print(" \t\t\t Welecome to Snake , Water , Gun game\n\n")

computer_point=0
while (attempts<=10):
lst=["snake","water","gun"]

if inp==ran:
print("tie")
print(f"you choosed {inp} and computer guess is {ran}")
print("No body gets point\n")
elif inp=="snake" and ran=="water":
your_point=your_point+1
print(f"you choosed {inp} and computer guess is {ran}")
print("The snake drank water\n")
print("You won this round")
print("you get 1 point\n")

your_point = your_point + 1

I am attempting to make a basic rock, paper, scissors game. When I input either rock, paper, or scissors, I sometimes have to enter the same thing multiple times for it to continue to the if statements. See code below:
# Rock, Paper, Scissors
player_total = 0
computer_total = 0
def get_computer_hand():
choice = randint(1, 3)
if choice == 1:
return "scissors"
elif choice == 2:
return "paper"
else:
return "rock"
def ask_user():
global player_total
global computer_total
player = input("Enter your hand (stop to stop): ")
if player == "stop":
print("Computer had ", computer_total, "points, you had ", player_total, " points.")
exit(0)
computer = get_computer_hand()
if player == "rock":
if computer == "paper":
return "win"
elif computer == "scissors":
return "lose"
else:
return "tie"
elif player == "paper":
if computer == "paper":
return "tie"
elif computer == "scissors":
return "lose"
else:
return "win"
elif player == "scissors":
if computer == "scissors":
return "tie"
elif computer == "paper":
return "win"
else:
return "lose"
def count_winner():
global player_total
global computer_total
player_total = 0
computer_total = 0
while True:
outcome = ask_user()
if outcome == "win":
print("You won that one.")
player_total += 1
elif outcome == "lose":
print("Computer won that one.")
computer_total += 1
count_winner()
I expect it to work the first time and to continue as usual, but I can't seem to figure out why it just asks "Enter your hand (stop to stop): " instead sometimes when I enter either rock, paper, or scissors.
This is happening because there is a tie happening between the computer and the user. This could be fixed by adding the end with the code of
else outcome == "tie":
print("You have tied with the Computer!")
computer_total += 1
player_total += 1
This would add a point to both sides and if you don't want that just delete the last two lines of my code
I was wondering if someone could tell me how to have the computer choose a new choice after every round. I got the lower portion of the code to cover all choices but it turns out my code runs where the computer uses the same choice every time. Is there a way to set my code so the computer chooses something new from the list. Thanks!
import random

Move this inside your while loop:
computerChoice = random.choice(gameList)
Currently you are saving a single choice, and then using it every time. Where as this would create a new choice each time:
while userScore < 2 and computerScore < 2:
userAnswer = input("Please choose Rock, Paper, or Scissors: ")
computerChoice = random.choice(gameList)
# Compare to see who won.
Note that gameList must be available inside that scope, so you will have to either pass it in as a function parameter or include it inside the function. That does change the nature of the function somewhat:
def game():
print("Welcome to Rock, Paper, Scissors. You are playing against the computer on best out of three game, winner takes all! Have Fun!")
userScore, computerScore, rounds = game_loop()
def game_loop(available_options: list=["Rock", "Paper", "Scissors"]):
computerScore = 0
userScore = 0
rounds = 0
while userScore < 2 and computerScore < 2:
userAnswer = input("Please choose Rock, Paper, or Scissors: ")
computerChoice = random.choice(available_options)
// compare and score (preferably in their own functions)
return userScore, computerScore, rounds
try this
import random
def computerChoice():
gameList = ["Rock", "Paper", "Scissors"]
return random.choice(gameList)
def userChoice(computerChoice):
userScore = 0
computerScore = 0
rounds = 0
print("Welcome to Rock, Paper, Scissors. You are playing against the computer on best out of three game, winner takes all! Have Fun!")
while userScore < 2 and computerScore < 2:
userAnswer = input("Please choose Rock, Paper, or Scissors: ")
#all your if statements and stuff
computerChoice = computerChoice()
print(userChoice(computerChoice()))
