Simple utilities that extend the Turtle module

This code extends the turtle module with context managers for the following tasks:

• turtle.penup
• turtle.pendown
• turtle.color
• turtle.pencolor
• turtle.fillcolor
• turtle.speed
• turtle.fill
• turtle.poly
• turtle.pensize
• disable_autoupdate
• enable_autoupdate

In addition to a save_postscript function to save the current canvas as an eps file.

Installation

pip install turtle-tools

Example

import turtle
import turtle_tools

turtle_tools.extend_turtle()

pen = turtle.Turtle()

with disable_autoupdate():
    for i in range(2):
        with pen.fill(), pen.color("blue", "green"):
            for i in range(4):
                pen.forward(100)
                pen.right(90)

        with pen.penup():
            pen.forward(150)

with pen.pensize(5):
    pen.right(90)
    pen.penup()
    pen.forward(200)
    with pen.pendown():
        pen.forward(100)
    pen.right(90)
    pen.forward(200)
    pen.pendown()
    pen.forward(200)

for i in range(2):
    with pen.poly(), pen.color("red"):
        for i in range(4):
            pen.forward(100)
            pen.right(90)

    with pen.penup():
        pen.forward(10)

save_postscript("file.eps")
turtle.done()
