trying to export both columns and rows to excel for a query like , select * from customer where customer_id=2323234

Question

I'm trying to print both columns and rows for select query-ex:

select * from customer where customer_id=2323234


for r, row in enumerate(cursor.fetchall()):
    for c, col in enumerate(row):
        sheet.write(r, c, col)

the above logic is writing only row but not column or headers into excel

to export both rows and columns to excel from python.
