Lab 6: Drawing with Functions

Use turtle graphics in our BTT CS 111 replit ( bit.ly/replitcs111 ) to draw squares using functions with parameters.

Today's quiz is in Zybooks 3.25 (8 minutes)
The project for this lab is at: https://replit.com/team/BTT-CS-111/Lab-6-Drawing-Squares-With-Functions

At the end of lab take a screen of your completed work paste it onto your group's page in today's shared google slides. Include a screen shot of the graphics as well as pasting the text of only the functions you implemented (not the rest of the program).

Results of running all six functions are shown at left.
You should implement the functions one at a time.
You may not have time to get to the last two, which is why they are considered extra credit.

Getting Started Python Code for the Lab (access on the replit site)

Lab 6: Use a function to draw multiple squares. Take screen shots and store

the results from each step on your slide in the shared google slides deck.

Each implemented function is worth half a point.
