turtle module Simple graphics programming How to use it ? Import turtle module by including import turtle Need to create a turtle, and NAME it to manipulate Say, you named a turtle xxx. xxx = turtle.Turtle() Opens up a turtle window Can have more than one turtles at a time tell them apart by names
turtle module >>> import turtle >>> t = turtle.Turtle() What is . between turtle and Turtle() ? turtle => class (generic object referring to turtle module) Turtle() => method (action, function, constructor) Rough interpretation: get turtle type (class) and do Turtle() >>> t.color( red ) Get turtle t and color it red Attribute Position, heading (direction), color, tail position
turtle module Actions t.forward(100), t.backward(100) t.right(90), t.left(45) t.goto(-200,90), t.circle(50), t.color( red ) t.up(), t.down() t.write( Hello! ) References http://www.eg.bucknell.edu/~hyde/Python3/TurtleDirections.html Official Python turtle page https://docs.python.org/release/3/library/turtle.html
turtle module Suppose turtle t is created Draw a circle --- t.circle(100) Draw a thicker circle t.width(5) Find out the location (x,y) of t t.position() Move t to (100,-50) t.goto(100,-50) Stop drawing t.up() Find out the screen sizes screen=t.getscreen() screen.window_width() and screen.window_height()
