What changes are you trying to make? (e.g. Adding or removing code, refactoring existing code, adding reports)

I added in both functions and comments for the assignment as it was outlined.

What did you learn from the changes you have made?

I learned how to open files and conduct manipulations/calculations on data that was inside each of those files.

Was there another approach you were thinking about making? If so, what approach(es) were you thinking of?

There are many ways that we could have manipulated the data and accomplished what the assignment was asking. In particular, we could have used a different library (e.g., pandas) to do the computations.

Were there any challenges? If so, what issue(s) did you face? How did you overcome it?

A couple of times I was not as familiar with the NumPy functions so I had to go an look at the documentation on the website.

How were these changes tested?

I used the built in testing from the assignment description as well as iteratively tested my code while I was creating the solution.
