Figure C-1: Two colorful spirals created with a three-

line program, thanks to the colorspiral.py module

With the colorspiral module, anytime a programmer wants to

create colorful spirals, all they have to do is import the module and

call colorspiral.cspiral()!

r using the colorspiral Modulee

Let’s reuse the colorspiral module to draw 30 random, colorful

spirals. To do that, we’ll import another module we’ve used before,

random. Type the following eight lines of code into a new file in

IDLE and save the file as SuperSpiral.py.

SuperSpiral.py

import colorspiral

import random

for n in range(30):

sides = random.randint(3,6)

size = random.randint(25,75)

x = random.randint(-300,300)

y = random.randint(-300,300)

colorspiral.cspiral(sides, size, x, y)

This program begins with two import statements: one for the

colorspiral module we created and the other for the random module

we’ve used throughout the book. The for loop will run 30 times.

The loop generates four random values for the number of sides
