The following is a short quiz just to refresh on various concepts learnt so far.

Introduction to Python Graphics using Turtle

“Turtle” is a python feature like a drawing board, which lets you command a turtle to draw all over it! You can install it using the following command sudo apt-get install python3-tk.

You can use functions like turtle.forward(…) and turtle.left(…) which can move the turtle around.

Here are some of the commands that you can use:

Turtle Function	Description
turtle.left(x)	turns left by x pixels
turtle.right(x)	turns right by x pixels
turtle.forward(x)	moves forward by x pixels
turtle.backward(x)	moves backward by x pixels
turtle.goto(x,y)	repositions to the location x,y in the drawing board
turtle.color(“color”)	changes the color from black to “color”

Remember x is a integer/float value in pixels.

Before you can use turtle, you have to import it.

Play around and learn more .

Copy paste the following code snippet to the trinklet window and see what happens.

import turtle 

pattern = turtle.Turtle()

pattern.pencolor("blue")

for i in range(50):
    pattern.forward(50)
    pattern.left(123) # Let's go counterclockwise this time 
    
pattern.pencolor("red")
for i in range(50):
    pattern.forward(100)
    pattern.left(123)
    
turtle.done()

Challenge:

a. Create a beautiful abstract pattern. Use for loops and/or while loops as necessary.
(or)
b. Animate a biological concept of your choice.
