Answer 1

you can use it :

    import csv

    with open('names.csv', 'w') as csvfile:
        fieldnames = ['first_name', 'last_name']
        writer = csv.DictWriter(csvfile, fieldnames=fieldnames)

        writer.writeheader()
        writer.writerow({'first_name': 'Baked', 'last_name': 'Beans'})
        writer.writerow({'first_name': 'Lovely', 'last_name': 'Spam'})
        writer.writerow({'first_name': 'Wonderful', 'last_name': 'Spam'})
