Lab 03: Experiments with Turtle
Our book has some nice content using turtle, such as this
activity,
but doesn’t involve enough problem solving with it.
So, I created a custom lab which involves turtle, random, and just
a bit of problem solving.
Instructions
Choose any code block from the book. Something from the Drawing a
Circle with the
Turtle
activity would be fitting, but it doesn’t really matter.
You need to write code that satisfies the following requirements:
- Randomly choose a number between 1 and 10 (inclusive), call it
n.
- In a loop, create
n turtles.
- For each turtle:
- Assign them a random color.
- Choose a random radius from 50, 75, 100, 125, 150
- Have the turtle draw a circle with that radius and color
- At the end, print total and average distance travelled
Note: Each turtle should choose its color and radius independently
of the other turtles.
When you are done, raise your hand and show me your code.
Hints
- In addition to our book’s chapters on
turtle and random, you
will probably need to skim Python’s official documentation for the
turtle module and
for the random
module.
- To draw a circle, learn about
turtle’s circle
method.
- You will need just a little bit of chapter
6
content to create a list of possible radii, and maybe a list of
possible colors. Luckily, we’ll cover enough of that right before
lab.
- To choose an item randomly from a list, learn about
random’s
choice
method.
- To figure out the area a turtle traveled, you’ll need to use the
formula for the circumference of a circle.
- To compute the total distance all turtles have traveled, you’ll
need to have a separate variable that starts at 0 and gets added to
inside your loop. This is your first example of the accumulator
pattern. Don’t be afraid to ask for help about this.
