Python project to sort the database columns and do some calculations.

I have a python code that fetches data from my database and sorts the data as per column value, and also implements a sort within those sorted values. I need someone to modify my algorithm to include more columns from database to sort. And to calculate the total of area and volume (available in database) of the sorted items.
We can discuss more on meeting and I can show an example what I am expecting as the output.
