Implement in python

Question

I have an Excel document, this document has 7 columns and 700 rows; At the first step, I want to compute for example x[i]+y[i] for each row and save them into an array variable.
after that, I want to export it into an Excel file.
I want to implement this process in python.

What is the best solution for this?
Thank you.

Answer 1

And what is x[i], y[i]?

Answer 2

I recommend xlrd ( pip install xlrd), then first line of your code or function should be :
import xlrd
