Looping with GASP Exercises

Objectives:

• You will practice creating while loops
• You will integrate loops into drawing graphics with GASP

Resources:

• GASP Reference

Directions:

• Use the following template in a file named loopGasp.py:

from gasp import *
#begin_graphics()
begin_graphics(width=800, height=600, title="Crazy Drawing", background=color.WHITE)

x = 0
while x < 1000:
    print x
    Circle ( (0, 0), x)
    x = x + 10

update_when('key_pressed')
end_graphics()

• What do you see when you run the code above?
• Let's try to create some other graphics with GASP and loops. Complete the following drawings, but you must create new files for each (e.g. loopGasp1.py, loopGasp2.py, etc.)

1. Draw a bunch of Circles across the bottom of the screen
2. Draw Circles along all the sides of the screen (left, bottom, right, top)
3. Draw a diagonal of Circles from the bottom-left to the upper-right
4. Draw 100 Circles of random sizes and random locations throughout the screen (HINT: random.randint())
5. Draw 10 random Circles, but each time you draw a Circle, connect a Line from it to the previous Circle
