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

Made changes to assignment 2 notebook. I added codes to the subroutines.

What did you learn from the changes you have made?

I learnt how to read lines from a file using python and how to use numpy to calculate mean, min and max

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

For this assignment I was following the lines that says 'YOUR CODE HERE:...' which was very convenient. So, I was mostly focused on writing code that was requested.

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

It was my first time learning about readlines(). I wasn't sure how to loop through readlines(), but after reviewing the slides and doing a bit of searching I realized that for loop and readlines() in python work well together.

How were these changes tested?

I ran the test cases, and I also added extra test cases. For the mean, min and max, I uploaded the first csv file ( inflammation_01.csv) to Google spreadsheet and calculated the mean, max and min. Then I compared the values. For the detect_problems() subroutine, I created an extra test case. On my local system, I changed the first row of inflammation_06.csv to all zeros so the mean for the first patient would be zero, and detect_problems() would return True.
