Answer 1

Thanks kroolik It's done with little modification.

with ZipFile(your_zip_file, 'w', ZIP_DEFLATED) as zip_file:
    string_buffer = StringIO()
    csvwriter = csv.DictWriter(string_buffer, delimiter=',', fieldnames=fieldnames)
    csvwrite.writeheader()
    for row in cdrdata:
        csvwrite.writerow(row)
    zip_file.writestr(filename + '.csv', string_buffer.getvalue())

Answer 2

Use the cStringIO.StringIO object to imitate a file:

with ZipFile(your_zip_file, 'w', ZIP_DEFLATED) as zip_file:
    string_buffer = StringIO()
    writer = csv.writer(string_buffer)

    # Write data using the writer object.

    zip_file.writestr(filename + '.csv', string_buffer.getvalue())
