# To uncomment code, remove the '# ' in the Python code. Take care to preserve
# the proper indentations.
#
+#
+# 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
+# Note: See http://docs.python.org/tutorial/datastructures.html
