Shape Module

Shape Module

In this lab we will create a set of drawing function and put them together into a new file. We will then import this file into our main.py file.

Example code to import the module in main.py

import turtle
from shape import *
dan = turtle.Turtle()
dan.shape('turtle')

draw_triangle(dan, 'red', 5, 20, 30)

draw_circle(dan, 'orange', 10, 0, 30)

draw_square(dan, 'orange', 15, -20, 30)

# This is a custom module we've made.  
# Modules are files full of code that you can import into your programs.
# This one teaches our turtle to draw various shapes.
