My third commit will consist of my third round of changes. What has changed during my third commit were my functions. In this attempt I was given feedback to consider how can I add more parameters or loops to my existing code. I did both by adding customizable parameters to allow a house and sun of any color. I also added a for loop that gives me three houses of different color instead of one.

What got me stuck in the beginning was how can I add more parameters or loops to my existing code.
What I figured out was that by adding more parameters and loops to my existing code I would be able to create a drawing that would give me three house and a sun
with customizable color of my choosing. A strategy I used to get unstuck was to continue using ideas from previous lessons about parameters and trial and error to
 see where things went right and wrong. What I wonder is how can I use super turtle to create an animated sun. What I want to learn more about is how to properly
 use super turtle. Since I have more houses and sun with customizable color my future project idea could be to create three houses and a sun with customizable
 coloring but this time using super turtle to creaete an animated rising sun.
