More turtle challenges

Random Polygons

Take the random square example from this page and change it so that it draws polygons of a random side number (between 3 and 12)

Temple of Doom

Using turtle.goto(), turtle.penup() and turtle.pendown() - together with a function to draw a shape, can you draw a whole series of shapes one inside the other.

---

MultiStar

Here the challenge is to create a function with a parameter that tells the function whether or not to fill in the star.  You can then draw outlined figures by calling the function twice - the first time filled in, the second as just an outline.

---

Versatile Square

This square function is centred on the current turtle position.

We save the current turtle position before we start drawing

def square(size):
    oldx = turtle.xcor()
    oldy = turtle.ycor()

Then lift the pen up, move half of the size value across, turn right and move half of the size value down.  That should put us at a corner.  Turn right again and draw the square normally.  When it's done, return to the home position using

   turtle.goto(oldx,oldy)
