Python 3 and DictWriter example:

import csv
from io import StringIO
from django.core.mail import EmailMessage

rows = [{'col1': 'value1', 'col2': 'value2'}]
csvfile = StringIO()
fieldnames = list(rows[0].keys())

writer = csv.DictWriter(csvfile, fieldnames=fieldnames)
writer.writeheader()
writer.writerows(rows)

email = EmailMessage(
        'Subject',
        'Body',
        'from@email.com',
        ['to@email.com'],
    )
email.attach('file.csv', csvfile.getvalue(), 'text/csv')
email.send()
