# testHw6.py
# D. Thiebaut
# This program tests all the functions for Homework 6.
# To use this program, simply write a program called hw6.py and
# store your functions in it. The functions are expected to be
# named function1(), function2(), etc.
# To test the the function, simply make sure that test6.py and
# hw6.py are in the same directory, and run test6.py. It will
# automatically import hw6.py and call the different functions,
# passing them parameters and checking the values returned by
# the functions.
import random # that's the module that allows us to pick random quantities
import hw6 # 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.
