Core Concepts

What is shape()?

shape('turtle')sets the turtle's shape.

`'circle'`	⚫	Circle
`'square'`	⬛	Square
`'triangle'`	🔺	Triangle

Try Visual Coding

○ Add a "shape" block and pick a different shape from the dropdown!

# Add blocks and the Python code will show up here...

Add blocks and the flowchart will show up here...

Example Code

import turtle

shape() syntax practice

Change to an arrow: t.shape('arrow')
Turning it into a circle: t.shape('circle')
A string QuotesWrap it with (' Or ")
