For substantial project tasks, two people will be assigned.

Person 1 is the actual implementer, and will write basic test functions for their code.

Person 2 will review the code of Person 1, and write additional test functions as needed.

According to PEP 8 docstrings should be included

for all public modules, functions, classes, and methods. Docstrings are not necessary for non-public methods, but you should have a comment that describes what the method does. This comment should appear after the def line.

At our October 21 group meeting, we decided to make sure we have comments

1. at the start of a class definition (to explain the purpose of the class)
2. within the constructor (i.e., the __init__() definition (to explain nonobvious aspects of object construction)
3. at the start of user-facing functions (to explain nonobvious aspects of function construction)

Regular comments (i.e., those preceded by #) are brief in-line comments to fellow developers to help understand how the code works.
