We Keep Coding

I have a bug in my program that I cannot figure out

So, I just recently started coding and decided to make a rock paper scissors game; However, my program has a bug where if the user enters "rock" the correct code block doesn't run. Instead it runs an else statement that's only meant to run when the user enters, "no". I tried using a while loop instead of just if else statements but it didn't make a difference.
import random
q_1 = str(input("Hello, want to play Rock Paper Scissors?:"))
print()
# ^^adds an indent
rpc_list = ["rock", "paper", "scissors"]
comp = random.choice(rpc_list)
# ^^randomly selects r, p, or s
user = str(input("Great, select Rock Paper or Scissors:"))
if q_1 != "yes":
if q_1 == comp:
print("Oh No, a Tie!")
elif q_1 == "rock":
if comp == "paper":
print("I Win!")
else:
print("You Win!")
elif q_1 == "paper":
if comp == "rock":
print("You Win!")
else:
print("I Win!")
else:
if comp == "rock":
print("I Win!")
else:
print("You Win!")
else:
print("Ok :(")

There are a few issues with your code.
First of all your code only plays the game if the user doesn't enter "yes". You need to change if q_1 != "yes": to if q_1 == "yes":.
Secondly, your code asks the user to choose rock, paper or scissors regardless of whether they have said they want to play or not. Fix this by moving user = str(input("Great, select Rock Paper or Scissors:")) to under the if q_1 == "yes": if statement.
Thirdly, your code uses q1 instead of user as it should.
Here is how your code should look:
import random
q_1 = str(input("Hello, want to play Rock Paper Scissors?:"))
print()
# ^^adds an indent
rpc_list = ["rock", "paper", "scissors"]
comp = random.choice(rpc_list)
# ^^randomly selects r, p, or s
if q_1 == "yes":
user = str(input("Great, select Rock Paper or Scissors:"))
if user == comp:
print("Oh No, a Tie!")
elif user == "rock":
if comp == "paper":
print("I Win!")
else:
print("You Win!")
elif user == "paper":
if comp == "rock":
print("You Win!")
else:
print("I Win!")
else:
if comp == "rock":
print("I Win!")
else:
print("You Win!")
print("I played:",comp)
else:
print("Ok :(")

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"

Adding the following code as the first line in each of the three computer_() functions should fix your problem.
global tied, user_score, computer_score
There are better ways to accomplish what you're doing, but that should get you over the hump here :)

While Triptych's answer is perfectly acceptable (and also widely used), for a relatively novice-level programmer it is usually better practice to pass arguments into functions instead of utilizing the global keyword.
More info can be found at the Python Documentation: https://docs.python.org/3/tutorial/controlflow.html#defining-functions
In essence, the point is for the programmer to pass what is called an argument (or arguments) into the function, and the function containing those parameters can process this data and return values back to the location where it was called, similar to how the print() function works. You pass a string (ex. "Hi") into the print() function (ex. print("Hi")), and code within this built-in function displays the characters "Hi" onto the screen.
In this case, your code would look something like this:
# In your main function:
def main():
print ("Let's play the game of Rock, Paper, Scissors. ")
while True:
print ("Your current record is", user_score, "wins,", computer_score, "losses and", tied, "ties")
computer_choice = random.randint(1,3)
if computer_choice == 1:
result = computer_rock(user_score, computer_score, tied) ## Notice the difference here
elif computer_choice == 2:
result = computer_paper(user_score, computer_score, tied) ## Those variables you put in the function call are arguments
else:
result = computer_scissors(user_score, computer_score, tied)
# ...
# In the computer_rock() function:
# Even though I only modified this function, you should probably modify all three to suit your needs.
def computer_rock(user_score, computer_score, tied): ## <-- See the parameters?
user_choice = input("1 for Rock, 2 for Paper, 3 for Scissors: ")
if user_choice == "1":
print ("Draw! You both chose Rock.")
tied += 1
try_again()
elif user_choice == "2":
print ("You Win! The computer chose Rock, while you picked Paper.")
user_score += 1
try_again()
elif user_choice == "3":
print ("You Lose! You chose scissors, while the computer picked Rock.")
computer_score += 1
try_again()
return [user_score, computer_score, tied] # Returning a list so it is easier to sort variables
Another thing to note, even though you are calling try_again() to restart the game, it is not a very good idea to call main() inside of a function that will be called by main(). It is better to use a while loop in the main function to regulate and control the flow of the program.
Hopefully this helped!

It caused from a feature in Python.
The following example emits the same Exception. Note that You can't assign to Global-Variable in Local-Scope.
>>> variable = 1
>>> def function():
... variable += 1
...
>>> function()
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "<stdin>", line 2, in function
UnboundLocalError: local variable 'variable' referenced before assignment
So if you write as the following, the value of Globale-Variable is not changed. This variable in function() is not Global-Variable but Local-Variable. Right?
>>> variable = 1
>>> def function():
... variable = 2
...
>>> function()
>>> variable
1
By the way, this feature is useful for us, because we want to use functions as small as possible, if speaking loudly, simply because we humans don't understand long functions.
Perhaps you want to use the Global-Variable here now, but when you write many and many codes, and can use Global-Variable, you will be panic such as "Where did this variable change?" because there are many places you changed.
If we have codes which we can't know where we change, these codes will be mysterious codes. It's so disgusting.
#Triptych 's answer is also right. If you adopt his answer, this codes will work. However I recommend that you don't use global.
p.s. You can do it in JavaScript.

I'm making a textual RPG, and I'm running into a problem. So in the code below, mobHP is a global variable, which is equal to 20000. This is only a part of the code. So what's happening is that once the attack takes place, the new HP of the monster is shown, but then by the second attack, the HP again becomes 20000 and then the damage is subtracted, and again another value is shown, it isin't subtracting from the new value itself. battlem() is the battle menu from where you can attack, use potions and run. win() is a def function to what to show when the user wins.
For example if a player hits the monster by 1000, then the currentHP will show as 19000, but then when I attack again, say hit by 1400, instead of 19000-1400, it subtracts from the original value, and becomes 18600.
Help would really be appreciated
def Attack():
damage = random.randint(120,240) - random.randint(80,120)
currentHP = 0
currentHP -= damage
input()
print("You swing your sword at the enemy!")
print("Inflicted damage:",damage,"enemy HP:",currentHP)
if playerHP <= 0:
death()
elif mobHP <= 0:
win()
else:
battlem()
currentHP=mobHP;
while(currentHP>0):
battlem()
However, this doesn't work as the output is
You swing your sword at the enemy!
Inflicted damage: 95 enemy HP: -95
This was a solution that was given, but then removed, and when I further asked for a solution nobody replied again.

It's not clear what's causing the error from the code you posted, but from the behavior you describe it sounds like you're not defining mobHP as a global. Here's some example code.
mobHP = 20000
playerHP = 30000
def check_hps():
if mobHP <= 0:
win()
if playerHP <= 0:
lose()
def broken_attack():
attack_value = 100 # how hard you hit
mobHP -= attack_value
check_hps()
def fixed_attack():
global mobHP
attack_value = 100
mobHP -= attack_value
check_hps()
To demonstrate:
>>> mobHP
20000
>>> broken_attack()
>>> mobHP
20000
>>> fixed_attack()
>>> mobHP
19900
>>> fixed_attack()
>>> mobHP
19800
This code is, of course, really difficult to maintain. It is, however, pretty easy to implement. Contrast with:
class Actor(object):
def __init__(self, name, maxHP, min_dmg, max_dmg):
self.name = name
self.maxHP = maxHP
self.currentHP = maxHP
self.roll_dmg = lambda: random.randint(min_dmg, max_dmg)
def attack(self, other, retaliation=False):
other.currentHP -= self.roll_dmg()
if not retaliation:
other.attack(self, retaliation=True)
def run(self, other):
if random.random() >= 0.5:
return True

Any ideas?

The problem is arising due to
variable scope
You can check this question as well to clear your doubt regarding global or local scope:-
Python global/local variables
The variable
has_dynamite
is defined only inside the
start()
function. Therefore, it has only a local scope, to make it global define has_dynamite outside any functions and write your functions like this
def start():
global has_dynamite
Do this for all of the functions which use has_dynamite variable.
You can also pass the has_dynamite variable as a parameter to the function. ie instead of typing the above mentioned code, you can type
start(has_dynamite)
while calling the function, but be sure you include this parameter in the function definition also, otherwise it will show you an error
Here is the corrected code:-
from sys import exit
has_dynamite = True
has_sword = True
has_bow = True
