Please help with attribute error that pops up when the code is run.

Thanks in advance!

Here's the code:

# coding: utf-8

from scene import *
import random

choices = '🌚', '📄', '✂️'

class rps(Scene):
    def __init__(self):
        self.player = self.computer = None

    def setup(self):
        self.button = Button(Rect(self.size.w/2-60, self.size.h/1-150, 125, 125))
        self.button.background = Color(0,0,0,0)
        self.button.stroke = Color(0,0,0,0)
        self.button.image = 'Moon_2'
        self.button.action = self.rock_action
        self.add_layer(self.button)

        self.button1 = Button(Rect(self.size.w/2-60, self.size.h/1-290, 125, 125))
        self.button1.background = Color(0,0,0,0)

        self.add_layer(self.button1)

        self.button2 = Button(Rect(self.size.w/2-60, self.size.h/1-450, 125, 125))
        self.button2.background = Color(0,0,0,0)
        self.button2.stroke = Color(0,0,0,0)
        self.button2.image = 'Scissors'
        self.button2.action = self.scissors_action
        self.add_layer(self.button2)

    def rock_action(self):
        self.button.background = Color(0,0,0,0)
        self.player = '🌚'
        self.computer = random.choice(choices)

    def paper_action(self):

    def draw(self):
        background(0, 0.05, 0.2)
        self.root_layer.update(self.dt)
        self.root_layer.draw()

        if self.player == "🌚" and self.computer == "🌚":

        if self.player == "✂️" and self.computer == "✂️":

        if self.player == "📄" and self.computer == "📄":
            self.ruling = "Draw"

        if self.player == "🌚" and self.computer == "✂️":

        if self.player == "✂️" and self.computer == "📄":
            self.ruling = "Win"

        print(self.ruling)

run(rps(), PORTRAIT)

def get_ruling(player_choice, opponent_choice):

    elif player_choice == '🌚':

    elif player_choice == '📄':

it would be helpful when posting request to debug your code, if you also post the traceback! that way, you don't force ccc to copy/paste/run your code in order to help...

In __init__(), add the line self.ruling = None

In your init method, add self.ruling = None
It's basically just not defined

@Pythonistapro777 I think you need to start making more of an effort to debug your own code before you post here. If you post every problem you run into with no clear effort to debug made, it's kind of annoying to some users. Try googling for answers similar to yours. For example, search for "Attribute error Python" to find out more about what your error means and work from there.
