New page

'''Objectives:'''
* You will practice creating while loops
* You will integrate loops into drawing graphics with GASP

'''Directions:'''
* Use the following template in a file named '''loopGasp.py''':

<syntaxhighlight lang="Python">
from gasp import *
begin_graphics()

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

update_when('key_pressed')
end_graphics()
</syntaxhighlight>

* 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.)

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