Python Forum

Hello, I'm new to the forum! I'm having an issue with my double dice game code, I keep getting a syntax error. Help and any advice would be appreciated!

import random

def Dice():
    player_1=0
    Points1=0
    player_2=0
    Points2=0
    player_12=0
    player_22=0
    Points12=0
    Points22=0
    totalpoints1=Points1 + Points12
    totalpoints2=Points2 + Points22
    
rounds=1

while rounds !=4:
        print("Round"+str(rounds))
        player_1=dice_roll()
        player_12=dice_roll()
        player_2=dice_roll()
        player_22=dice_roll()
        print("Player one rolls a: " + str(player_1 + player_12))
        print("Player two rolls a: "+ str(player_2+ player_22))

        if player_1 +player_12 ==player_2+player_12:
            print("It's a tie!")
        
        elif player_1+ player_12>player_2 + player_22:
            print("Player 1 wins!")
            totalpoints1 = totalpoints2 + 1
        else:
            print("Player 2 Wins!")
            totalpoints2 = totalpoints1 + 1

rounds=rounds+1

if Points1 + Points12 ==Points2 + Points22:
        print("It's a tie!")
elif Points1 + Points12 >Points2 + Points22:
        print("player 1 wins!")
else:
        print("Player 2 Wins!")

def dice_roll():
    diceRoll=random.randint(1,6)
    return diceRoll

There's a few problems here. Let's start with Dice(). What do you think this is doing? What is it's purpose?
I think you mean for Dice to be a structure that holds information for your dice game. Look what happens when I run this program:

def Dice():
    player_1=0
    Points1=0
    player_2=0
    Points2=0
    player_12=0
    player_22=0
    Points12=0
    Points22=0
    totalpoints1=Points1 + Points12
    totalpoints2=Points2 + Points22

print('Dice is a', type(Dice))
print('Dice knows about', Dice.__dict__)
print(totalpoints1)

Output:
Dice is a <class 'function'>
Dice knows about {}
Traceback (most recent call last):
  File "C:/Users/djhys/Documents/Python/schema/dsp/regex.py", line 17, in <module>
    print(totalpoints1)
NameError: name 'totalpoints1' is not defined

Surprise! Dice is a function. The code above creates a function that assigns a bunch of local variables and returns None. And those local variables are only visible from inside the function while it is running. When I tried to print "totalpoints1" I got an error because there is no such thing outside the Dice function.

For a simple program like this I would forget about any kind of data structure until I got all the parts working. Something like this

import random
 
def dice_roll():
    return random.randint(1,6)

player1_points = 0
player2_points = 0

for rnd in range(1, 5):
    player1_roll = dice_roll() + dice_roll()
    player2_roll = dice_roll() + dice_roll()

    print('Round', rnd)
    if player1_roll == player2_roll:
        print("It's a tie!")
    elif player1_roll > player2_roll:
        print("Player 1 wins the roll!")
        player1_points += 1
    else:
        print("Player 2 wins the roll!")
        player2_points += 1

print('Game over')
if player1_points == player2_points:
    print("It's a tie!")
elif player1_points > player2_points:
    print("player 1 wins the game!")
else:
    print("Player 2 Wins the game!")

Output:
Round 1
Player 1 wins the roll!
Round 2
Player 1 wins the roll!
Round 3
Player 1 wins the roll!
Round 4
It's a tie!
Game over
player 1 wins the game!

I think the game is a little sterile. To give it some flash I change the dice rolling to report which die were cast. To do this I modified the dice_roll function.

def dice_roll(player_name):
    die1 = random.randint(1,6)
    die2 = random.randint(1,6)
    print(player_name, 'rolls', die1, 'and', die2)
    return die1 + die2

See how this adds drama.

Output:
Round 1
Player 1 rolls 2 and 4
Player 2 rolls 6 and 6
Player 2 wins!

Round 2
Player 1 rolls 4 and 6
Player 2 rolls 6 and 3
Player 1 wins!

Round 3
Player 1 rolls 6 and 5
Player 2 rolls 5 and 3
Player 1 wins!

Round 4
Player 1 rolls 4 and 6
Player 2 rolls 4 and 6
It's a tie!

Game over
player 1 wins the game, 2 to 1

Hi! Thank you for the reply & sorry for the late reply, but when I modified dice_roll function, I got an error:

File "C:/Users/FatherYeals/PycharmProjects/DiceGame2/Dice Game1.py", line 14, in <module>
player1_roll = dice_roll() + dice_roll()
TypeError: dice_roll() missing 1 required positional argument: 'player_name'

Guess that was a little confusing. To use the enhanced dice_roll function you would have to modify the function calls to provide 'Player 1' or 'Player 2'
