Rock Paper Scissors Game – Python Tkinter GUI Tutorial #144

In this video we’ll build a fun little “Rock, Paper, Scissors” game with Tkinter and Python.

This is a fun children’s game where you select either Rock, Paper, or Scissors and then match your pick vs. the computer to see who wins. Rock smashes Scissors, but gets covered by paper; Paper covers rock but gets cut by Scissors, and Scissors cuts paper but gets smashed by rock.

In this app we’ll use images, a ttk combbox, labels, buttons, random numbers, lists, and some basic if/else logic.

Python Code: rps.py
(Github Code)

from tkinter import *
from random import randint
from tkinter import ttk


root = Tk()
root.title('Codemy.com - Rock, Paper, Scissors')
root.iconbitmap('c:/gui/codemy.ico')
root.geometry("500x600")
# Change bg color to white
root.config(bg="white")

# Define our images
rock = PhotoImage(file='images/rps/rock.png')
paper = PhotoImage(file='images/rps/paper.png')
scissors = PhotoImage(file='images/rps/scissors.png')

# Add Images to a list
image_list = [rock, paper, scissors]

# Pick random number between 0 and 2
pick_number = randint(0,2)

# Throw up an image when the program starts
image_label = Label(root, image=image_list[pick_number], bd=0)
image_label.pack(pady=20)

# Create Spin Function
def spin():
	# Pick random numnber
	pick_number = randint(0,2)
	# Show image
	image_label.config(image=image_list[pick_number])

	# 0 = Rock
	# 1 = Paper
	# 2 = Scissors

	# Convert Dropdown choice to a number
	if user_choice.get() == "Rock":
		user_choice_value = 0
	elif user_choice.get() == "Paper":
		user_choice_value = 1
	elif user_choice.get() == "Scissors":
		user_choice_value = 2


	# Determine if we won or lost
	if user_choice_value == 0: # Rock
		if pick_number == 0:
			win_lose_label.config(text="It's A Tie! Spin Again...")
		elif pick_number == 1: # Paper
			win_lose_label.config(text="Paper Cover Rock! You Lose...")
		elif pick_number == 2: # Scissors
			win_lose_label.config(text="Rock Smashes Scissors!  You Win!!!")


	# If USer Picks Paper
	if user_choice_value == 1: # Paper

			win_lose_label.config(text="Paper Cover Rock! You Win!!!")

	# If User Pics Scissors
	if user_choice_value == 2: # Scissors

			win_lose_label.config(text="Rock Smashes Scissors! You Lose...")

			win_lose_label.config(text="Scissors Cuts Paper! You Win!!!")


# Make our choice
user_choice = ttk.Combobox(root, value=("Rock", "Paper", "Scissors"))
user_choice.current(0)
user_choice.pack(pady=20)

# Create Spin Button
spin_button = Button(root, text="Spin!", command=spin)
spin_button.pack(pady=10)

# Label for showing if you won or not
win_lose_label = Label(root, text="", font=("Helvetica", 18), bg="white")
win_lose_label.pack(pady=50)


root.mainloop()
