# To test the the function, simply make sure that testLab7.py and

# lab7.py are in the same directory, and run testLab7.py.  It will

# automatically import lab7.py and call the different functions,

# passing them parameters and checking the values returned by

# the functions.

This page contains the information regarding the Moodle submission for CSC 111 Lab #7. You have until 3/13 11:00 a.m. to submit your program.

Moodle Submission


  • Write python program called lab7.py that contains only the following functions you wrote for the last challenges of Lab 7:
  • isLeftSide()
  • isUpperHalf()
  • getColor()
  • Your program will contain only these 3 functions. No main function. No graphics required. Your program will be called from a test program that will test your three functions separately (see below).


Test Program


  • If you want to test your lab7.py using a similar test used by Moodle, simply create the program below in the same directory where you have stored lab7.py, and run it. It will test your lab7.py functions for you.
