Lesson 12: Making Patterns with Turtle

Topics Covered:

• Using loops to create repeated shapes
• Combining movements for patterns
• Changing colors and pen size

Using Loops for Patterns

Loops make it easy to draw repeated shapes or designs.

import turtle

t = turtle.Turtle()

for _ in range(36):
    t.forward(100)
    t.left(170)

turtle.done()

Changing Colors and Pen Size

You can change the drawing color and pen thickness:

t.color("blue")      # Change pen color
t.pensize(3)          # Set pen thickness

Creating a Star Pattern

import turtle

t = turtle.Turtle()
t.color("red")
t.pensize(2)

for _ in range(5):
    t.forward(100)
    t.right(144)

turtle.done()

Activity: Create Your Own Pattern

• Try changing the angles and steps in the loop
• Use different colors with t.color()
• Experiment with pen size and speed using t.pensize() and t.speed()

Challenge

Create a colorful flower by combining circles and loops:

import turtle

t = turtle.Turtle()
t.speed(10)

for _ in range(36):
    t.circle(100)
    t.left(10)

turtle.done()
