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

I read a data file, calculated some descriptive statistics (mean, min, max), and did a simple analysis (checking for zeros).

What did you learn from the changes you have made?

I learned how to import data, calculate statistics, and perform a simple analysis (e.g., checking for values that meet a certain criterion).

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

I was thinking about adding a for loop to the check_zeros helper function by iterating over each item in the array. It became a bit complicated. Then, I realized there is the np.where() function.

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

I learned that the np.where function can take only 1 or 3 arguments, not 2. I was stuck on that error for a while before I did some research and corrected the issue. I also had some issues when I tried to return the boolean and index for the check_zeros helper function. I was not able to return True and the index together. Whenever the output was true, I would just get the index. After doing some research, I learned that because tuples are truthy, 'True' is almost implied when the tuple is returned, so 'True' is not included in the output.

How were these changes tested?

I did some extra tests in additional code blocks labelled 'Extra testing'. I basically took the output from each operation within the function to print it and troubleshoot. That way, I know how the information was flowing through the function.
