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.
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.
# testLab7.py
# D. Thiebaut
# This program tests all the functions for Lab 7.
# To use this program, simply write a program called lab7.py and
# store your functions in it. The functions are expected to be
# named isLeftSide(), isUpperHalf(), and getColor().
# 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.
import sys
import random # that's the module that allows us to pick random quantities
import lab7 # that's your hw6.py module. We don't add ".py" to modules,
# but the file containing the program must have ".py" at the end.
