For this task, we want you to get some practice writing code at the most basic level, and also become familiar with the turtle and turtleBeads commands that can be used for drawing in Python.

The requirements are very simple, and in fact, there are no restrictions on what you draw: the only rules are that you must make use of certain functions.

To start, you need to create a new file, named scene.py. This file must be in a folder where turtleBeads.py is also present. To create that file, you should:

1. Download the starter code for this task from Potluck.
2. Unzip the downloaded file to create a folder to work in. This folder will include a file called turtleBeads.py.
3. In Thonny, create a new file. Immediately use "save" or "save as" and then pick the folder you just created as the destination, with "scene.py" as the filename.

Now you're ready to write code. Your scene.py file must satisfy the following criteria:

1. Your file must start with a triple-quoted string at the top, identifying the names of each author, which classmates and/or tutors and/or instructors you consulted for help, the last date you modified the file, and a brief description of the purpose of the file. We will do this for all files that you submit in this class. Here is an example:

   py """ Authors: Anon & Ymous Consulted: T. A. Date: 2022-9-8 Purpose: Turtle Scene task """

2. Your file must appropriately import the turtleBeads module. You will also need to import the turtle module separately to ensure that you can use the basic drawing commands.

3. You must use each of the following basic movement functions (reference) at least once:
   • forward (a.k.a. fd)
   • backward (a.k.a. bk or back)
   • left (a.k.a. lt)
   • right (a.k.a. rt) (this example provides a brief reminder of how these work).
4. You must use an absolute positioning command at least once (one of setx, sety, setpos/setposition/goto, or teleport).
5. You must use each of the following turtleBeads shapes (turtleBeads reference):
   • drawCircle (you may use the turtle function circle instead)
   • drawRectangle
   • drawText (you may use the turtle function write instead)
6. You must vary the thickness and colors of some lines, using both pensize and either pencolor or color (pen functions reference).
7. You must use begin_fill and end_fill to draw at least one filled-in shape, and you must use fillcolor (or color)) to control its color (fill reference; see also the example on filling).
8. You must use penup and pendown to move the turtle without drawing a line (or you may use the one or more of the teleport, leap, or hop functions from turtleBeads to achieve the same thing).
9. You must use the title function to assign a title to your graphics window (title reference).

You are welcome to use other turtle or turtleBeads features in addition to the ones listed above, but only the above features are required.

If you want to challenge yourself and read ahead a little bit, consider defining a custom function and using it as part of your turtle scene (but you will not receive any extra credit for this, so don't do it if you're short on time).

Note: to speed up the drawing when things get complex, you can use the noTrace and showPicture functions. You can read how they work in our turtle documentation.

After completing this task, you must take a screenshot of your graphics scene, name it correctly, and upload it to the shared google drive folder as explained in the submission instructions.
