Turtle Lab #$1$

General Directions

Turtle graphics comes with your Python compiler and is a graphical way to learn programming. In order to work with Turtle graphics you need to import the turtle library. From there you can make the turtle move on your screen. If you have not done so already, please read the material listed on Canvas that describes Turtle Graphics.

In this lab you will learn how to use the turtle class and its methods. You will utilize some basic commands in order to get your turtle to move on the screen. The end product is a short program, containing functions that will allow you to move the turtle.

The methods listed below are a part of the turtle class. They will allow you to move the turtle, draw shapes and add color.

Drawing Shapes

For your portion of the lab you will create a circle, square and a shape of your choosing. Initialize the turtle shape to be a turtle and the color to be green.

Create a circle that contains the following:

Fill color of your choosing

Pen Color in a contrasting color

Pen Size needs to be $10$

Size needs to be $100$ pixels

Drawn at $200,100$

Change the turtle back to green

Create a Square that contains the following:

Fill color of your choosing

Pen Color in a contrasting color

Pen Size needs to be $5$

Size needs to be $200$ pixels. This means that when you make

Create a Square that contains the following:

Fill color of your choosing

Pen Color in a contrasting color

Pen Size needs to be $5$

Size needs to be $200$ pixels. This means that when you make the turtle go forward it needs to go forward $200$ pixels.

Drawn at $-200,-200$

Change the turtle back to green

Create a shape of your choosing that is not a circle or square. You can draw a triangle, parallelagram, rectangle, etc. This shape needs to be different from the other shapes already drawn in the program in terms of location, fill color, pen color and size. Your file and pen color need to be different from your other shapes. The pen size also needs to be different from your other shapes.

Change the turtle back to green

Relocate the turtle to $0,0$ or the center of the screen.

Finished Drawing

My rendition of a circle, square and different shape looked like the following. Your output will be different since you are choosing different colors and your last shape will be different.

Handing In

Once your program is working upload your $.$py file to Canvas.
