  • This is a partner assignment. Knowing how to collaborate and work on teams is a vital skill that a computer scientist must learn.
  • To avoid losing 15 points, you must complete this assignment with a classmate and you must both submit the same solution to the Portal.
  • To avoid losing an additional 5 points, explain your contributions to the solution in your solution’s comment box.

Ecosystem Simulation - 100 points

In this assignment, you will modify this Python program (rename according to the instructions below) so that it can be used to draw a simulated ecosystem such as this. (Note: to see the full black border that surrounds the Python turtle graphics window, you will need to manually expand the window slightly.)

To complete this assignment, you will need to use the turtle and random modules. In addition, you will gain a deeper understanding of functions.

Requirements and Grading

  • 10 points - The correct number of animals appear.
  • 10 points - Each animal can be any random color.
  • 10 points - Each animal can be in any random orientation.
  • 10 points - Each animal can be stamped at any random coordinate within the Python turtle graphics window.
  • 10 points - The black boundary box around the Python turtle graphics window appears correctly.
  • 10 points - The create_animal function works correctly as specified in the comments.
  • 10 points - The draw_boundary function works correctly as specified in the comments.
  • 10 points - The stamp_animal function works correctly as specified in the comments.
  • 10 points - A comment block appears for the write_message function, in the same format as the other function comment blocks.
  • 10 points - The code you write is high quality.

Submission

Place the solution in a file named ecosystem_firstname.py and submit it in the Portal no later than 12:45 PM on Thursday, November 30.
