Create unique CSVs named for each iteration of my for loop

Question

Using Python to execute a series of SQL queries, and would like the output of each iteration of my query to be exported as its own csv file.

For example:

clients = ['Ellen','Jose','Tina']

for client in clients:
    print(client)
    with open('/sales.csv', 'wt') as outfile:
        dw=csv.writer(outfile)
        dw.writerow(['index', 'client','product','sales'])
    query = """
    SELECT '{}' as client, 
       product,
       COUNT(1) AS sales
  FROM datasource
  GROUP BY 1, 2
  ORDER BY 3 DESC 
  LIMIT 100""".format(market,market)
    with open('sales.csv'.format(client,client), 'w') as output:
      output.write(client)

I want a filename of say sales_ellen.csv, sales_jose.csv -- I know this isn't doing it (it's appending each one in the sales.csv file). thanks

Just change your open statement to format in the name of the client:

with open('/sales_%s.csv'%client, 'wt') as outfile:
