Graphics: The Hollow Circle

     You guessed it--that's graphics. When you zoom in very, very far, you'll see a ton of tiny blocks. Well, of course, these are pixels, picture elements. Everything virtual has these, from the computer to the Wii.
     Let's make our own graphics!
     Well, we all know the black screen of black screens. Open that up and edit the program to this.


import pygame, sys
pygame.init()
screen=pygame.display.set_mode([640, 480])
screen.fill([255, 255, 255])
pygame.draw.circle(screen, [255, 0, 0], [100, 400], 30, 10)
pygame.display.flip()
while True:
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            sys.exit()


     Colors. They're hard to explain. ([255, 255, 255]) and [255, 0, 0] is computer for white and red. Here's the 5 steps to creating a shape:
Surface
On what "surface" to draw the circle (in our case, screen).
Color
What color the circle will be.
Location
Where on the surface the circle will appear.
Size
Self-explanatory. The size (the radius measured by pixels).
Width
How thick the line is. If the thickness is 0, it will be a solid circle.
     Yeah, it's Valentines Day. What's the theme? Red and White are Valentine colors. That's all I got. It's not easy for something like this.

Remember, EVERYTHING is measured by pixels.

     I challenge you to experiment with the colors. Here's a tip: There are always 3 sets of numbers.
