Objectives:
- You will practice creating lists of turtles
- You will integrate loops and lists into drawing graphics with Python's turtle
Resources:
Directions:
- Use the following template in a file named listTurtle.py:
from turtle import *
#speed(0) # fastest turtle
#create empty list of turtles
turtles = []
#populate the list of turtles with 10 turtles
x = 0
while x < 10:
turtles.append(Turtle())
x = x + 1
#do stuff with turtles
#you'll need to use the loop
x = 0
while x < 10:
turtles[x].forward(x * 10)
x = x + 1
exitonclick()
- What do you see when you run the code above?
- Let's try to create some other graphics with Turtle, lists, and loops. Complete the following drawings, but you must create new files for each (e.g. listTurtle1.py,listTurtle2.py, etc.)
- Tell each turtle to draw a circle using its element/index number
- Tell each turtle to go to a random location and draw a random circle
- Tell each turtle to go to a random location and move forward a random distance between 50-200
- Create 20 turtles and place them 15 units apart from each other vertically
