Start IDLE
============

Run::

  >>> import turtle as t
  >>> t.write('hello world')


Lists & Loops
================

Create a list with some numbers in it. Loop over the list and move the turtle with each number.

Functions
=========

Write a function (``square``) that draws a square

Write a function (``move_xy``) that moves the turtle to certain coordinates

Call both functions like this::

    >>> for x, y, size in [(10, 10, 5),
    ...     (-20, -20, 10)]:
    ...     move_xy(t, x, y)
    ...     square(t, size)



Conditionals
============

Write a function (``odd_square``) that takes a number:

* if the number is odd it moves right and up that amount and draws a square
* if the number is even it moves right and down that amount and draws a square

Call it like thes::

  >>> for num in range(10):
  ...     odd_square(num)

File io
=======

Read in a text file and have the turtle write out the contents

Classes
=======

Make a ``Rabbit`` subclass of ``Turtle``:
* when ``.pensize`` is called, double the size of the pen
* when ``.forward`` is called, go twice the amount
* when ``.backward`` is called, go back half the amount

Run::

  >>> r = Rabbit()
  >>> t2 = t.Turtle()

  >>> for thing in [r, t2]:
  ...     for num in range(100):
  ...         thing.forward(num)
  ...         thing.left(2)
  ...         thing.backward(num/2)
