The terminal says that computer_choice doesn’t exist even though it does

WHile I was attempting a simple rock, paper scissors, I ran into this proble. When I execute the file and input the user_input, it says to me that the variable computer_choice doesn’t exist, even though it does exist. I would appreciate if someone could help me, thank you.
import random
user_wins = 0
computer_wins = 0
options = ["rock", "paper", "scissors"]
while True:
user_input = input("Type Rock/Paper/Scissors or Q to quit. ").lower()
if user_input == "q":
break
if user_input not in options:
continue
random_number = random.randint (0, 2)
computer_choice = options[random_number]
print ("The computer picked:", computer_choice + ".")
if user_input == "rock" and computer_choice == "scissors" :
print("You Won!")
user_wins += 1
continue
elif user_input == "scissors" and computer_choice == "paper" :
print("You Won!")
user_wins += 1
continue
elif user_input == "paper" and computer_pick == "rock" :
print("You Won!")
user_wins += 1
continue
else:
print("You Lost!")
computer_wins += 1
continue
print("You won", user_wins,"times and the computer won", computer_wins, "times.")
print("Goodbye")

You have to be careful with indentation when using python:
import random
user_wins = 0
computer_wins = 0
options = ["rock", "paper", "scissors"]
while True:
user_input = input("Type Rock/Paper/Scissors or Q to quit. ").lower()
if user_input == "q":
break
if user_input not in options:
continue
# not at this level
# at this level
random_number = random.randint(0, 2)
computer_choice = options[random_number]
print("The computer picked:", computer_choice + ".")
if user_input == "rock" and computer_choice == "scissors":
print("You Won!")
user_wins += 1
continue
elif user_input == "scissors" and computer_choice == "paper":
print("You Won!")
user_wins += 1
continue
elif user_input == "paper" and computer_choice == "rock": #not computer_pick
print("You Won!")
user_wins += 1
continue
Also you wrote computer_pick in line 31, probably you mean computer_choice

Why isn't my variable showing as defined?

I'm trying to make "Rock, Paper, Scissors" as my second program. I keep encountering an error,

As you can maybe see, my variable, rps_choice, is not defined, even though it was defined and returned from the rps_input() function. I really have no clue as to why this is happening.

You meant to capture the returned value in rps_choice:
rps_choice = rps_input()
Also, I see you have rps_input() called on two different lines. Both these lines will need updating.

Because you defined it inside the function rps_input() so it belongs only to that function. Imagine it as a hierarchy, the variables from downer scopes can access the variables from upper scopes but it doesn't go the other way.

my rock paper scissors gives me nothing in output (python)

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")
import random
attempts= 1
your_point=0
computer_point=0
while (attempts<=10):
lst=["snake","water","gun"]
ran=random.choice(lst)
print("what do you choose snake, water or gun")
inp=input()
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")
elif inp=="water" and ran=="snake":
computer_point = computer_point + 1
print(f"you choosed {inp} and computer guess is {ran}")
print("The snake drank water\n")
print("You Lost this round")

print(f"you choosed {inp} and computer guess is {ran}")
computer_point = computer_point + 1

Rock Paper Scissors Running Twice Error

I'm new to programming. I have written code for the rock paper scissors game but there is one bug that I can't seem to fix. When the game closes, the user is asked if he wants to play again. If the user answers yes the first time, then plays again then answers no the second time, the computer for some reason asks the user again if he wanted to play again. The user must enter no in this case. This is because although the user answers no, the answer gets reset to yes and goes over again. How can this be fixed?
# This code shall simulate a game of rock-paper-scissors.
from random import randint
from time import sleep
print "Welcome to the game of Rock, Paper, Scissors."
sleep(1)
def theGame():
playerNumber = 4
while playerNumber == 4:
computerPick = randint(0,2)
sleep(1)
playerChoice = raw_input("Pick Rock, Paper, or Scissors. Choose wisely.: ").lower()
sleep(1)
if playerChoice == "rock":
playerNumber = 0
elif playerChoice == "paper":
playerNumber = 1
elif playerChoice == "scissors":
playerNumber = 2
else:
playerNumber = 4
sleep(1)
print "You cookoo for coco puffs."
print "You picked " + playerChoice + "!"
sleep(1)
print "Computer is thinking..."
sleep(1)
if computerPick == 0:
print "The Computer chooses rock!"
elif computerPick == 1:
print "The Computer chooses paper!"
else:
print "The Computer chooses scissors!"
sleep(1)
if playerNumber == computerPick:
print "it's a tie!"
else:
if playerNumber < computerPick:
if playerNumber == 0 and computerPick == 2:
print "You win!"
else:
print "You lose!"
elif playerNumber > computerPick:
if playerNumber == 2 and computerPick == 0:
print "You lose!"
else:
print "You win!"
replay()
def replay():
sleep(1)
playAgain = "rerun"
while playAgain != "no":
playAgain = raw_input("Would you like to play again?: ").lower()
if playAgain == "yes":
sleep(1)
print "Alright then brotha."
sleep(1)
theGame()
elif playAgain == "no":
sleep(1)
print "Have a good day."
sleep(1)
print "Computer shutting down..."
sleep(1)
else:
sleep(1)
print "What you said was just not in the books man."
sleep(1)
theGame()

This is because of the way the call stack is created.
The First time you play and enter yes to play again, you are creating another function call to theGame(). Once that function call is done, your program will continue with the while loop and ask if they want to play again regardless if they entered no because that input was for the second call to theGame().
To fix it, add a break or set playAgain to no right after you call theGame() when they enter yes
while playAgain != "no":
playAgain = raw_input("Would you like to play again?: ").lower()
if playAgain == "yes":
sleep(1)
print "Alright then brotha."
sleep(1)
theGame()
break ## or playAgain = "no"

You should break out of the loop after calling theGame. Imagine you decided to play again 15 times. Then there are 15 replay loops on the stack, waiting to ask you if you want to play again. Since playAgain is "yes" in each of these loops, each is going to ask you again, since playAgain is not "no"

How to create a Rock, Paper, Scissors program

I'm very new to python and am taking an online class. I'm not very familiar with many functions in python so if you could keep it somewhat basic for me to keep track of, I would really appreciate it. I am trying to make a program that runs Rock, Paper, Scissors with a user but the num_games is not being accepted in the "for i in range". Also, I have run it and found that Scissors can beat Rock (THIS IS ANARCHY!). Can anyone assist me? Thanks in advance!
import random
def comp_turn():
comp_move = random.randint(1,3)
if comp_move == 1:
return "Rock!"
elif comp_move == 2:
return "Paper!"
else:
return "Scissors!"
def main():
num_games = int(input("Enter how many games you would like to play: "))
print "You are going to play " + str(num_games) + " games! Here we go!"
num_wins = 0
for i in range(num_games):
user_move = input("Choose either Rock, Paper or Scissors and enter it: ")
cpu_turn = comp_turn()
print "The computer went with: " + cpu_turn
if user_move == 'Rock' and cpu_turn == 'Scissors':
print "You won! Nice job!"
num_wins +=1
elif user_move == 'Paper' and cpu_turn == 'Rock':
print "You won! Nice job!"
num_wins +=1
elif user_move == 'Scissors' and cpu_turn == 'Paper':
print "You won! Nice job!"
num_wins +=1
elif user_move == cpu_turn:
print "Oh! You tied"
else:
print "Whoops! You lost!"
return num_wins
print main()

This should be what you want:
import random
def comp_turn():
return random.choice(['Rock','Paper','Scissors'])
def main():
num_games = int(input("Enter how many games you would like to play: "))
print("You are going to play " + str(num_games) + " games! Here we go!")
num_wins = 0
for i in range(num_games):
user_move = input("Choose either Rock, Paper or Scissors and enter it: ")
cpu_turn = comp_turn()
print("The computer went with: " + cpu_turn)
if user_move == 'Rock' and cpu_turn == 'Scissors': print("You won! Nice job!"); num_wins +=1
elif user_move == 'Paper' and cpu_turn == 'Rock': print("You won! Nice job!"); num_wins +=1
elif user_move == 'Scissors' and cpu_turn == 'Paper': print("You won! Nice job!"); num_wins +=1
elif user_move == cpu_turn: print("Oh! You tied")
else: print("Whoops! You lost!");
return num_wins
print(main())
Or even Better:
import random
def comp_turn():
return random.choice(['Rock','Paper','Scissors'])
def main():
num_games = int(input("Enter how many games you would like to play: "))
print("You are going to play " + str(num_games) + " games! Here we go!")
num_wins = 0
winning=[('Rock','Scissors'),('Paper','Rock'),('Scissors','Paper')]
for i in range(num_games):
user_move = input("Choose either Rock, Paper or Scissors and enter it: ")
cpu_turn = comp_turn()
print("The computer went with: " + cpu_turn)
if (user_move,cpu_turn) in winning:
print('You won!')
num_wins+=1
elif user_move == cpu_turn:
print('Same')
else:
print('You lost!')
return num_wins
print(main())
And another option that's also good:
import random
def comp_turn():
return random.choice(['Rock','Paper','Scissors'])
def main():
num_games = int(input("Enter how many games you would like to play: "))
print("You are going to play " + str(num_games) + " games! Here we go!")
num_wins = 0
d={}.fromkeys([('Rock','Scissors'),('Paper','Rock'),('Scissors','Paper')],'You Won')
for i in range(num_games):
user_move = input("Choose either Rock, Paper or Scissors and enter it: ")
cpu_turn = comp_turn()
print("The computer went with: " + cpu_turn)
if not user_move == cpu_turn:
print(d.get((user_move,cpu_turn),'You lost!'))
else:
print('Same')
return num_wins
print(main())

Here's what you want:
import random
outcome = random.choice(['Rock', 'Paper', 'Scissors'])
print(outcome)

Have you tried removing the '!' in the comp_turn function? It seems like cpu_turn variable will contain either 'Rock!', 'Scissors!' or 'Paper!' while your if-else condition is looking for either 'Rock', 'Scissors' or 'Paper' without the '!'. So, no matter what the player or cpu chooses, it will go into 'else' in the 'for' loop and the player loses.
This is the edited code:
import random
def comp_turn():
comp_move = random.randint(1,3)
if comp_move == 1: return "Rock"
elif comp_move == 2: return "Paper"
else: return "Scissors"
def main():
num_games = int(input("Enter how many games you would like to play: "))
print("You are going to play " + str(num_games) + " games! Here we go!")
num_wins = 0
for i in range(num_games):
user_move = input("Choose either Rock, Paper or Scissors and enter it: ")
cpu_turn = comp_turn()
print("The computer went with: " + cpu_turn)
if user_move == 'Rock' and cpu_turn == 'Scissors':
print("You won! Nice job!")
num_wins +=1
elif user_move == 'Paper' and cpu_turn == 'Rock':
print("You won! Nice job!")
num_wins +=1
elif user_move == 'Scissors' and cpu_turn == 'Paper':
print("You won! Nice job!")
num_wins +=1
elif user_move == cpu_turn:
print("Oh! You tied")
else: print("Whoops! You lost!")
return num_wins
print(main())
Do note that the player's input is case sensitive too. Hope this helps!
