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

File handling includes open/read csv file, numpy functions to get mean, max, min value for the data being processed.

What did you learn from the changes you have made?

Python file functions, numpy library as well as error handling, etc.

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

Without numpy, much more code could have been developed for realizing the same functionality, it would be time consuming and not efficient.

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

With detailed instructions from the instructor and TA team, all have been done successfully.

How were these changes tested?

Wrote the test code to display the result to verify if meet the expectation.
