Open CSV file and writing each row to new, dynamically named CSV file

Question

I have a csv file with, say, 50 rows of data, and I would like to split it into separate csv files for each row, which includes first row (header) and the the relevant row.

You can use DictReader too...

import csv

counter = 1

with open('mock_data.csv', 'r') as csvfile:
    reader = csv.DictReader(csvfile)
    for row in reader:
        filename = "file_%s" % str(counter)
        with open(filename, 'w') as csvfile_out:
        writer = csv.DictWriter(csvfile_out, fieldnames=reader.fieldnames)
        headers = dict((n, n) for n in reader.fieldnames)
        writer.writerow(headers)
        writer.writerow(row)
        counter = counter + 1
