I'm having an issue with my programming of Rock, Paper, Scissors for Python. My issue occurs when there is a tie. When there is a tie, my program is supposed to going into a while loop within the if statement of the tie and reask the player the same question, rock, paper or scissors again until it breaks out of the tie. I have attached the link to the image of the issue:
In Round 5: you can see the issue.
I am taking an intro to programming class so I'm still a beginner and I do not know what I am doing wrong.
A Python program for the Rock, Paper, Scissors game.

Your problem comes from the way you have structured your control statements (if, elif, else). When you enter your tie while loop, you are constantly running it until someone wins and that looks like it works no problem. The issue is that once you do that, the python interpreter skips all elif and else statements in that control block (if I say if x == 3: do this else: do that) I don't want python to follow through with the else condition if x does indeed == 3). Sorry if that is confusing, long story short you need to make sure that even when your tie block gets executed you still move on to scoring the round and starting a new one. The easy way to do that is just change the elif (player == "r") to an if statement. That way the interpreter treats the scoring control sequence as its own block and it will always be executed once you assign the throws each player makes.
Example:
def f(x):
if (x == 0):
print("1")
x += 1
elif (x == 1):
print("2")
print("Done!")
def g(x):
if (x == 0):
print("1")
x += 1
if (x == 1):
print("2")
print("Done!")
if you call f(0):
Python will print out 1 and then Done!
if you call g(0):
Python will print out 1 then 2 then Done!
Your immediate problem is that you have the handling code for a tie in the same if/elif chain as the handling for the other scoring.
You say something like:
if tied
stuff
elif player == r
...
As a result, when there is a tie the game correctly loops until there is no tie. But then is skips over the code that updates the score, because that is how if/elif/else works!
An immediate fix would be to break that if/elif chain, and put the tie-handling into a separate if block:
if tied:
loop until not tied
# now do scoring
if player == 'r':
... etc
With that said, let me add a few more things:
You are assigning two values to the same variable, in sequence:
computer = 'rock'
computer = 'r'
This doesn't do anything, because the second overwrites the first. You should just delete the first line in each of those pairs.
You should probably write a function that repeatedly asks the user to pick one, until it gets either rock, paper, or scissors. Use a while loop.
There is a function in the random module that will pick an item from a list, tuple, or string and return it. You can use that to make the computer pick r,p,s directly.
You can simplify your code by determining the outcome in advance. Say you have the computer pick first. Then if the computer picks 'r', you know 'p' is a win and 's' is a lose. Store the win/lose picks in a pair of variables, and all your testing can be boiled down to one test:
computer = computer_pick()
if computer == 'r':
winner = 'p'
computer = 'rock'
elif computer == 'p':
...
player = player_pick()
if tied ...
if player == winner:
print("Computer picked", computer, "- you win!")
else:
...

I was writing code for Rock Paper Scissors game in Python. This is kinda tournament style (3 rounds)
But it just keeps playing after the 3rd round is over.
def play():
player = input("Please type 'r' for Rock, 'p' for Paper and 's' Scissors: \n").lower()
while (player != 'r') and (player != 'p') and (player != 's'):
player = input("That is not an valid option. Please try again:\n").lower()
computer = random.choice(['r', 'p', 's'])
commands = {
"r" : "Rock",
"p" : "Paper",
"s" : "Scissors"
}
if player == computer:
print("It's a draw! Game Over.")
return("Draw")
elif user_win(player, computer):
print(f"You won! The computer used {commands[computer]} against your {commands[player]} and lost.")
return("Won")
print(f"You lost! The computer used {commands[computer]} against your {commands[player]} and won.")
return("Lost")
def user_win(player, computer):
# r > s, s > p and p > r
if (player == 'r' and computer == 's') or (player == 's' and computer == 'p') or (player == 'p' and computer == 'r'):
return True
print("Hello, Player! Choose your weapon.")
count, user, comp = 0, 0, 0
while count < 3:
count =+ 1
outcome = play()
if outcome == 'Won':
user =+ 1
elif outcome == 'Lost':
comp =+ 1
if user > comp:
print(f"You win. You: {user} Computer: {comp}")
elif comp > user:
print(f"You lost. You: {user} Computer: {comp}")
else:
print(f"Its a draw. You: {user} Computer: {comp}")
This is the full code. Below is the part which have problem (if i understood it right)
while count < 3:
count =+ 1
outcome = play()
if outcome == 'Won':
user =+ 1
elif outcome == 'Lost':
comp =+ 1
Ps: This is my first time posting on stackoverflow so sorry if i posted in wrong way.
The error is count =+ 1. Try count += 1, that should work.
(As a little background: count =+ 1 will simply assign a value of 1 to the variable count. After that, count never chnages, so it can never reach 3, and you're stuck in an infinite loop. The increment you want is count += 1.)
When you do
count =+1, it just assigns the value +1 to variable count, which is less than the required exit value of 3. You can try to log the value of count across iterations for a better understanding.
Fix:
Change the =+ to += for what I suppose is your requirement, ie to increment value by 1 on each iteration. Read through What is the difference between '+=' and '=+'?
I have written the below code for a rock, paper, scissors game as my first bit of independent coding. I've tried every possible solution I can possibly think of to get a cumulative running total of wins, losses and draws, however every time it only shows me the most recent result - i.e. 1 win 0 losses 0 draws even on the 50th game if the most recent game was a win.
Can anybody suggest a way to solve this?

Thank you!
If you want to save a variable outside of all the functions, and modify it inside a function, you can use the Python global keyword. Otherwise, when you try to modify the variable inside a function, even if you defined it already outside the function, Python will assume you meant to create a brand-new variable, with its scope only function-level, and the variable with global scope won't be modified. To specify that you want to modify the global variable, you can use
global <variable_name>
as the first line in your function. That way, Python knows that any references to variable_name inside your function refer to the "global" variable (outside the function).
Disclaimer: using global variables is generally regarded as a Bad Idea. It makes it more difficult to fix issues with your code, since any code could possibly be modifying your global variables, which makes it harder to keep track of where it could be going wrong. For more info, see Why are global variables evil?
Wherever possible, you should try to find another solution. In this case, the solution in #JNevill's comment is probably a better idea.
I'm trying to create a rock paper scissors game for a class assignment with Python, but I can't get the result out.
The game is supposed to start with the 1) user's input, 2) show what computer randomly chose, 3) the result (You win, You lose, or Tie with how you won or lost), 4) then ask if you want to Play again, and 5) finally escape.
I did succeed on the first 2 parts, but I can't figure out why 3, 4, 5 is not printing...
The result after showing what the computer played(2), it says 'None' then it loops back to (1) getting the input from the user.
Below is the code. Please advise me on how to fix them. Thank you so much!!
import random

player = input("Enter a number (0 for rock, 1 for paper, 2 for scissors) >>")

print("Tie!")

I am creating a rock, paper, scissors game. I want it to be best of 3 matches and to be able to verify user input. I keep running into issues with the user input. I have tried multiple variations but I can't seem to figure it out. I know my code is probably messy, so any input on how to clean it up would be greatly appreciated. Thank you so much for your time.

Since I had a few minutes to kill with a cup of coffee, here's a rewrite of your program with a bunch of improvements, the validation you asked about and some tips on coding style:

"The tournament will be the best of 3 wins.\n"
"It will be you against our highly intelligent computer opponent.\n"
"Good luck!")
# to avoid repeating these values over and over and changing numbers in to string,
# just defining them here. Name in capitals because it's global (generally bad)
# an even nicer solution would be to write a Game() class and put everything in
# there, but it would be a bit more advanced

1: 'Rock',
2: 'Scissor',
3: 'Paper'
}
def get_user_choice():
# keep asking until a valid value is returned
while True:
# this is a bit fancy, but let's say you want to reuse the game for similar games
# with different options from rock, scissor, paper, you'd want this code to still work
# get a list of string versions of the numbers
numbers = list(map(str, RSP_OPTIONS.keys()))
# join them together like you presented them: 1, 2 or 3
options = ', '.join(numbers[:-1]) + ' or ' + numbers[-1] + ':\n'
# add the descriptions
options = options + ''.join(f'{n}: {name}\n' for n, name in RSP_OPTIONS.items())
try:
user_choice = (int(input("-------------------------------------------\n"
f"Enter choice by typing {options}"
"-------------------------------------------\n")))
except ValueError:
# any invalid option
user_choice = -1
# check if it's one of the valid options
if user_choice in RSP_OPTIONS:
return user_choice
else:
# it makes sense to generate a new line where you want it, instead of having
# to put new line characters at the start of other strings
print("Please pick a valid number\n")
def beats(choice1, choice2):
# choice1 beats choice2 if it's one greater, except when choice2 == 3 and choice1 == 1
# but to make it even nicer and have it work for other similar games, you could say
# "except when choice1 == the max choice and choice2 == the min choice"
return (choice2 - choice1 == 1 or
(choice1 == max(RSP_OPTIONS.keys()) and choice2 == min(RSP_OPTIONS.keys())))

# instead of exiting hard, maybe just return, telling the caller we don't want to play again
return False
else:
# you were calling play_game again, but that causes the game to get more and more calls
# on top of each other, ultimately reaching an error state
# by returning first and then calling again, you avoid that problem
return True
# the function returns whether it should play again
while play_game():
pass
# once it leaves the loop, the game stops automatically here, no more code
There's still a lot of room for improvement though; try implementing some more advanced forms of RSP, or make the computer more intelligent than just playing random, but have it use some kind of strategy, perhaps with a bit of randomness mixed in.
And code-wise, try separating the game from the way it is presented on the screen; what if you decided to do this on the web instead of on a console, or in a graphics window? You could also consider putting all the code in a nice class, getting rid of global variables and allowing you to create more copies of the game as needed.
I am working on a rock paper scissors game. Everything seems to be working well except the win/loss/tie counter. I have looked at some of the other games people have posted on here and I still cannot get mine to work. I feel like I am soooooo close but I just can't get it! thanks for any help guys. this is my first time posting in here so I am sorry if I messed up the formatting.
I edited the code but still cannot get the program to recognize the counter without using global variables. at one point of my editing I managed to get it to count everything as a tie... i dont know how and I lost it somewhere along my editing. lol. -thanks again everyone!
here is what I get when I run the program:

else:
tie += 1
return result
main()
Your winner_result function returns before it increments the win counters. If you remove all the return statements from it, the counters should be updated. The return statements aren't needed anyway because the if/elif/else structure ensures that only one of the possible outcomes will be executed.
As Junuxx says in a comment, you also need to assign values to the winner_result variable properly, i.e. winner_result = 'win' instead of winner_result == 'win'. I'd also rename the winner_result variable or the function, because it's confusing to have both use the same name.
And the win/lose/tie variables are currently local, which means that main and winner_result will have their own copies of these variables, so main's values will always be zero. What you can do is make them global variables: Assign them to zero in the global scope (outside any function), and add the line global win, lose, tie inside the function winner_result.
Obviously been a few years since this question was answered but it came up while I was looking the same info. Here's my code if anyone is interested.
#! usr/bin/python3
import random
def game():
computer_count = 0
user_count = 0
while True:
base_choice = ['scissors', 'paper', 'rock']
computer_choice = random.choice(base_choice)
user_choice = input('(scissors, paper, rock) Type your choice: ').strip().lower()
print()
computer_wins = 'The computer wins!'
you_win = 'You win!'
print(f'You played {user_choice}, the computer played {computer_choice}')
if user_choice == 'scissors' and computer_choice == 'rock' or \
user_choice == 'paper' and computer_choice == 'scissors' or \
user_choice == 'rock' and computer_choice == 'paper':
print(computer_wins)
computer_count += 1
elif user_choice == 'rock' and computer_choice == 'scissors' or \
user_choice == 'scissors' and computer_choice == 'paper' or \
user_choice == 'paper' and computer_choice == 'rock':
print(you_win)
user_count += 1
else:
if user_choice == computer_choice:
print('Its a draw!')
computer_count += 1
user_count += 1
print(f'Computer: {computer_count} - You: {user_count}')
print()
game()
I was trying to do the same project, and I have found a solution that works well for me.
from random import randint
win_count = 0
lose_count = 0
tie_count = 0
# create a list of play options
t = ["Rock", "Paper", "Scissors"]
# assign a random play to the computer
computer = t[randint(0, 2)]
# set player to false
player = False
print()
print("To stop playing type stop at any time.")
print()
while player == False:
# set player to True
player = input("Rock, Paper or Scissors? ")
if player.lower() == "stop":
print()
print(
f"Thanks for playing! Your final record was {win_count}-{lose_count}-{tie_count}")
print()
break
if player.title() == computer:
print()
print("Tie!")
tie_count += 1
print()
elif player.title() == "Rock":
if computer == "Paper":
print()
print(f"You lose. {computer} covers {player.title()}.")
lose_count += 1
print()
else:
print()
print(f"You win! {player.title()} smashes {computer}.")
win_count += 1
print()
elif player.title() == "Paper":
if computer == "Scissors":
print()
print(f"You lose. {computer} cuts {player.title()}.")
lose_count += 1
print()
else:
print()
print(f"You win!, {player.title()} covers {computer}.")
win_count += 1
print()
elif player.title() == ("Scissors"):
if computer == "Rock":
print()
print(f"You lose. {computer} smashes {player.title()}.")
lose_count += 1
print()
else:
print()
print(f"You win! {player.title()} cuts {computer}.")
win_count += 1
print()
else:
print()
print("Sorry, we couldn't understand that.")
print()
# player was set to True, but we want it to be false to continue loop
print(f"Your record is {win_count}-{lose_count}-{tie_count}")
print()
player = False
computer = t[randint(0, 2)]
This works (kinda)
there are many issues with the code at the top of the page.
Firstly, Scoring doesn't work.
Secondly, nothing is indented meaning that nothing inside of the other def functions will work.
Thirdly, The other def functions are referred to in the first def main statement which causes Python to show an invalid syntax due to Python not knowing the other functions as they were referred to before they were introduced to python.
