Python Turtle Cheet Sheet!
turtle.up(): Sets the pen state to be up (not drawing).
turtle.down(): Sets the pen state to be down (drawing).
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 (counter
clockwise) 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.color(r,g,b), turtle.color(s) / turtle.fillcolor(r,g,b)
turtle.fillcolor(s): Sets the color of the line / fill color that the pen will use until the
color / fill color is changed.
It Takes
1. three arguments, each a floating-point number between 0.0—1.0, where the first
indicates the amount of red, the second, the amount of green, and the third the amount of blue.
OR
2. a “color string” – the name of a Tk color (e.g., “black”, “red”, “blue”, …)
The default pen color and fill color is “black”.
turtle.circle(radius): Draws a circle of the indicated radius. The turtle draws the circle
tangent to the direction the turtle is facing.
turtle.begin_fill(), 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(), 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.
turtle.xcor(), turtle.ycor(): Returns the x-coordinate / y-coordinate of the current
pen position.
turtle.bye(): Close the turtle drawing window
