Add a S.No column in CSV file

[naveen521kk]

I think we need to add an S.No column in CSV file as it would be quite helpful while checking between SQL and CSV. What do you think @Aathish04

I don't think it's necessary, as we can just count the number of rows at runtime.

I had an option to set auto_increment of rows in sql. It might be quite helpful. If CSV file also has one.

I achieved that with

rows= [
            (csv_reader.line_num-1,)+tuple(
                row[fieldname] for fieldname in csv_reader.fieldnames
            )for row in csv_reader
        ]
