Python Turtle Module
Cheat Sheet


Turtle Pen --

turtle.up()
Sets the pen state to be up (for no drawing).

turtle.down()
Sets the pen state to be down (for drawing).

turtle.color(r,g,b)
* See Below

turtle.color(s)
Sets the color that the pen will draw until the color is
changed. It takes either...
1. three arguments, each a floating point number between
0.0 - 1.0, where the first the amount of red, the second is
the amount of green, and the third is the amount of blue
2. a "color string" the name of a TK color (e.g., "black",
"red", "blue", ...)

<!...>

turtle.begin_fill()
* See Below

turtle.end_fill()
To fill a figure, use turtle.begin_fill() before you start
drawing the figure. Draw the figure. Then execute
turtle.end_fill(). The figure drawn between the two fill
commands will be filled with the present color setting.

turtle.hideturtle()
* See Below

turtle.showturtle()
Sets the state to hide / show the turtle. When shown, you
see it as a small arrowhead pointed in the direction of the
heading.
The default pen color is "black".


Turtle Draw --

turtle.right(degrees)
Turns the direction that the turtle is facing right
(clockwise) by the amount indicated (in degrees).

turtle.left(degrees)
Turns the direction that the turtle is facing left
(counterclockwise) by the amount indicated (in degrees).

turtle.forward(distance)
Moves the turtle forward (in the direction the turtle is
facing) the distance indicated (in pixels).
Draws a line if the pen is down, not if the pen is up.

turtle.backward(distance)
Moves the turtle backward (in the direction opposite to
how the turtle is facing) the distance indicated
(in pixels).
Draws a line if the pen is down, not if the pen is up.

<!...>

turtle.setheading(angle)
Sets the orientation of the turtle to angle. Here are some
common directions in degrees:
0 (east)
90 (north)
180 (west)
270 (south)

turtle.goto(x,y)
Moves the turtle to the specified coordinates, drawing a
straight line to the destination (x,y) if the pen is down,
and not drawing if the pen is up.

turtle.circle(radius)
Draws a circle of the indicated radius. The turtle draws the
circle tangent to the direction the turtle is facing.


Turtle other --

turtle.xcor(), turtle.ycor()
Returns the x - coordinate / y - coordinate of the current
pen position.

<!...>

turtle.bye()
Close the turtle drawing window
