Adding code to complete assignment 2

What did you learn from the changes you have made?

Learned how to read csv files, make an array, use numpy to perform mathematical operations and also making functions to examine presence of mean zeros in these arrays.

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

No

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

I had to double-check numpy manual to see how the check_zeros function works in detecting zeros

How were these changes tested?
