Example Python Homework

An example homework assignment in Python for demonstrating how homework is done in the course.

In this (example) assignment we will learn some basic Python. In particular, we will learn about basic Python arithmetic, list handling, and how to create Python modules as well as an introduction to writing tests using Python's unittest module.

Objective

Provide definitions to the functions square and cube defined in the Python submodules example_homework.squaring and example_homework.cubing, respectively.

def square(x):
    # return the square of x
    
def cube(x):
    # return the cube of x

The provided example test suite can be executed using

$ python ./test_example_homework.py

As always, you are welcome (and encouraged) to add your own tests to the test suite to ensure that your code is robust. Most of all, make sure that the supplied tests pass so that the grading software can import and use your function as expected.

Grading

When the homework deadline is reached your implementation of square and cube will be run against the following tests:

• (1/5) the square and cube of zero is zero (already in the provided test suite)
• (1/5) the square and cube of two is four and eight, respectively (already in the provided test suite)
• (1/5) square and cube should behave appropriately with complex numbers as input (e.g. 1.0 - 2.0j)
• (2/5) these functions should also be able to act on Python lists of numbers without the use of the Python function map. that is, if the input is of type list then the output should also be of type list containing appropriate corresponding values

It is important that the function names and locations DO NOT CHANGE. Otherwise, the test suite used for grading may not be able to import your code. If it's importable in the test suite provided to you it should be importable in the grading test suite.
