Introduction
============
Turtle graphics is a popular way for introducing programming to kids. It was
part of the original Logo programming language developed by Wally Feurzeig,
Seymour Papert and Cynthia Solomon in 1967.
Turtle graphics is an implementation of `the popular geometric drawing tools
introduced in Logo <https://en.wikipedia.org/wiki/Turtle_
(robot)>`_, developed by Wally Feurzeig, Seymour Papert and Cynthia Solomon
in 1967.
In Python, turtle graphics provides a representation of a physical "turtle"
(a little robot with a pen) that draws on a sheet of paper on the floor.
It's an effective and well-proven way for learners to encounter
programming concepts and interaction with software, as it provides instant,
visible feedback. It also provides convenient access to graphical output
in general.
Turtle drawing was originally created as an educational tool, to be used by
teachers in the classroom. For the programmer who needs to produce some
graphical output it can be a way to do that without the overhead of
introducing more complex or external libraries into their work.
Get started
===========
Imagine a robotic turtle starting at (0, 0) in the x-y plane. After an ``import turtle``, give it the
command ``turtle.forward(15)``, and it moves (on-screen!) 15 pixels in the
