Lab 3: More Turtle and Loops

You have now been briefly introduced to two very powerful constructs in the Python programming language: for loops and functions. Today, we will try to solidify your understanding of these topics, and exploring more of what Turtle lets us do.

Polygons

In a file called Polygons.py, write a program that is able to draw arbitrary polygons to the turtle window. To accomplish this, you should write a function called draw_polygon(x, y, num_sides), which takes an x and y coordinate and the number of sides to draw the shape. It should use turtle to draw the shape in the specified location.

Spirograph

In a file called Spirograph.py, write a program that mimics the Spirograph devices that you likely remember from your childhood. Your program should have a function called draw_spirograph(side_length), which takes 1 integer as a parameter. It should use the information passed to the function to draw a spiral shape with the specified length of a side. Your Spirograph can have as many points as you wish, but it must contain more than 10, and have some circular space in the center that is empty.
