How to do reverse for it with two more numbers

Like subject one column
Marks 1st year marks one column
2nd year marks one column
Same subjects
For understanding I said same example

Actually I will use sales and profit in two columns
And category one column
Here category =subject

Hi Azar
Can you please have a video on generating header and trailer record using spark scala or python

Cnupodala

is there a way you can avoid hard-coding the subject-names for the final sum ?

thesadanand

when you are demonstrating a working code be sure your code is dynamic and not hard-coded column names. Overall it was good.
