My program won't run. Do I need to download python game program? Our instructor didn't say we did, so I assume not. Are each of my steps correct? There are six steps I did, and you'll see from the comments what part I did.

Below is the program!

# Drag to Draw Pygame program

# By C. Calongne 01/21/19

# Developed with tips from Pygame.com & Teach Your Kids to Code by Payne, 2015

# Six steps to complete in M4Lab2

# Define a list to store the colors

# Define statements for each mouse button

# Within the program suite, draw on screen with a different color

# When your program runs, a black box appears.

# Draw with a different color using the left, middle, and right cursor buttons

# The middle cursor is the scrollwheel. You can configure a random color.

# Close the draw window. In the Python shell, type exit() to quit

import pygame

import random # optional for this program, but useful for random colors, such as

# randcolor = random.randrange(0,255)

pygame.init()

# Defines the display size with a width and height of 600, 600

size = width, height = 600, 600

# Step 1: Define a colors list to describe 3 colors.

# Hint, use their RGB number values

Color_List= [BLACK( 0, 0, 0), WHITE ( 255, 255, 255), GREEN ( 0, 255, 0)]

screen = pygame.display.set_mode(size)

# Draws the screen using the size

pygame.display.set_caption("Click and drag to draw")

# Displays the title at the top of the draw screen

keep_going = True

# The program continues unti you close the window and type exit() in the shell

# Step 2: define a radius variable for your pen at 5, 10 or 15

# Test them to see which radius you prefer and use it.

radius= radius + 20

pen_size = pen_size + 5

mousedown = False

# we have not started drawing yet

while keep_going != False:

for event in pygame.event.get():

if event.type == pygame.QUIT:

keep_going= False

pygame.quit()

if event.type == pygame.MOUSEBUTTONDOWN:

mousedown = True

if event.type == pygame.MOUSEBUTTONUP:

mousedown = False

if mousedown: # start drawing

spot = pygame.mouse.get_pos() # locate the pen's position as the 1st spot

if pygame.mouse.get_pressed()[0]: # Boolean for button 1

button_color = colors[0] # selects the first color from the list

# Step 3: write the elif for pressing button 2, similar to button 1

if pygame.mouse.get_pressed()[2]: # Boolean for button 2

# Step 4: write the statement for button 2's color

button_color = colors[2]

# Step 5: write the else statement for button 3

if pygame.mouse.get_pressed()[2]: # Boolean for button 3

# Step 6: choose a color from the list

button_color = colors[3]

pygame.draw.circle(screen, button_color, spot, radius)

# The pen is in the shape of a circle that draws on the screen

# using the button color, the position of the spot, and the pen's radius

pygame.display.update()

# You can draw until you close the Pygame window

pygame.quit()

# Does the program continue to run?

# Type print(keep_going) or another variable to test it.

# The program ends after you type exit() in the Python shell.

# For fun, try defining a random color and calling it for button_color

# randcolor = random.randrange(0,255)
