-# This procedure is invoked when the user-definable block on the "extras"
-# palette is selected. Some examples of how to use this block are included
-# below. Try uncommenting an example or write your own Python code.

-# To uncomment code, remove the '# ' in the Python code. Take care to preserve

-#
-#
-# NOTES:
-#
-# Turtle Art is created in object oriented Python code. This is based
-# around the definition of classes and the creation of object(s) which
-# are instance(s) of that class. These objects then have properties and
-# methods which are defined by their class.
-#
-# See http://docs.python.org/tutorial/classes.html for a description of
-# classes in Python.
-#
-# Class Defined in Instance Created in
-# TurtleArtWindow tawindow.py tw TurtleArtActivity.py
-# LogoCode talogo.py lc tawindow.py
-# TurtleGraphics tacanvas.py canvas tawindow.py
-# Turtles, Turtle taturtle.py turtles tawindow.py,
-# tacanvas.py
-# Blocks, Block tablock.py block_list tawindow.py

-# Class TurtleArtWindow -- useful properties and methods (from within
-# tamyblock.py, lc.tw is the class instance)
-#
-# Methods and data attributes Example
-# set_fullscreen(self) lc.tw.set_fullscreen()
-# Note: Hides the Sugar toolbar
-# set_cartesian(self, flag) lc.tw.set_cartesian(True)
-# Note: True will make the overlay visible;
-# False will make it invisible
-# set_polar(self, flag) lc.tw.set_polar(True)
-# Note: True will make the overlay visible;
-# False will make it invisible
-# hideshow_button(self, flag) lc.tw.hideshow_button()
-# Note: Toggles visibility of blocks and palettes
-# self.active_turtle lc.tw.active_turtle
-# Note: The active turtle instance
-#
-#
-# Class TurtleGraphics -- useful properties and methods (from within
-# tamyblock.py, lc.tw.canvas is the class instance)
-#
-# Methods and data attributes Example
-# clearscreen(self) lc.tw.canvas.clearscreen()
-# Note: Clears the screen and resets all turtle and
-# pen attributes to default values
-# setpen(self, flag) lc.tw.canvas.setpen(True)
-# Note: True will set the pen "down", enabling drawing;
-# False will set the pen "up"
-# forward(self, n) lc.tw.canvas.forward(100)
-# Note: Move the turtle forward 100 units
-# arc(self, a, r) lc.tw.canvas.arc(120, 50)
-# Note: Move the turtle along an arc of 120 degrees
-# (clockwise) and radius of 50 units
-# setheading(self, a) lc.tw.canvas.setheading(180)
-# Note: Set the turtle heading to 180
-# (towards the bottom of the screen)
-# self.heading lc.tw.canvas.heading
-# Note: The current heading
-# setpensize(self, n) lc.tw.canvas.setpensize(25)
-# Note: Set the turtle pensize to 25 units
-# self.pensize lc.tw.canvas.pensize
-# Note: The current pensize
-# setcolor(self, c) lc.tw.canvas.color(70)
-# Note: Set the pen color to 70 (blue)
-# self.color lc.tw.canvas.color
-# Note: The current pen color
-# setshade(self, s) lc.tw.canvas.shade(50)
-# Note: Set the pen shade to 50
-# self.shade lc.tw.canvas.shade
-# Note: The current pen shade
-# fillscreen(self, c, s) lc.tw.canvas.fillscreen(70, 90)
-# Note: Fill the screen with color 70, shade 90 (light blue)
-# setxy(self, x, y) lc.tw.canvas.setxy(100,100)
-# Note: Move the turtle to position (100, 100)
-# self.xcor lc.tw.canvas.xcor
-# Note: The current x coordinate of the turtle
-# (scaled to current units)
-# self.ycor lc.tw.canvas.ycor
-# Note: The current y coordinate of the turtle
-# (scaled to current units)
-# self.set_turtle(name) lc.tw.canvas.set_turtle(1)
-# Note: Set the current turtle to turtle '1'
-#
-#
-# Other useful Python functions
-# Module Example
-# from math import pow pow(2,3) returns 2 to the 3rd power
-# Note: See http://docs.python.org/library/math.html
-# from math import sin, pi sin(45*pi/180) returns sin of 45 (0.707)
-# Note: See http://docs.python.org/library/math.html
-# from time import localtime localtime().tm_hour returns the current hour
-# Note: See http://docs.python.org/library/time.html
-# lc.heap.append(data) adds data to the heap
-# Note: See http://docs.python.org/tutorial/datastructures.html
-# data = lc.heap.pop(-1) pops data off the heap
