Turtle Pen
turtle.up() |
Sets the pen state to be up (not drawing). |
turtle.down() |
Sets the pen state to be down (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 other
turtle.xcor(), turtle.ycor() |
Returns the x - coordinate / y - coordinate of the current pen position. |
turtle.bye() |
Close the turtle drawing window |

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 (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. |

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