Studying for Python Mid-Term

So I will have my mid-term for my Python class soon and I wanted to share a script that will most likely be on the test.

This semester we have been working a little with Pygame, and this script uses Pygame to load an image and essentially change the color of the image depending on the color temperature. Here is what I have:

	import pygame, sys
	from pygame.locals import *
	pygame.init()
	grey = (150, 150, 150)
	lite_grey = (220, 220, 220)
	blue = (80, 144, 154)
	dark_blue = (0,50,77)
	lite_blue = (143,220,236)
	display_surface = pygame.display.set_mode((900,948))
	display_surface.fill(grey)
	image = pygame.image.load("image_before.png").convert()
	for x in range(900):
	for y in range(948):
	color_temp = image.get_at((x,y))
	temp_int = color_temp[0] + color_temp[1] + color_temp[2]
	integer = (max(color_temp[0], color_temp[1], color_temp[2]) + temp_int//2//3)
	if integer < 70:
	image.set_at((x,y),dark_blue)
	elif integer < 100:
	image.set_at((x,y),blue)
	elif integer < 130:
	image.set_at((x,y),lite_blue)
	else:
	image.set_at((x,y),lite_grey)
	pygame.image.save(image, 'image_after.png')
	while True:
	for event in pygame.event.get():
	if event.type == QUIT:
	pygame.quit()
	sys.exit()
	display_surface.blit(image, (0,0))
	pygame.display.update()

Here is what I got from this script:

Before and After

Pygame is still really new to me, but its really cool to be able to do this. Anyways, that's all for now, thanks for reading!
