A quick way to check if a list of files is complete

That's a pretty dumb way to do it, but I'm tired. It involves touch, however, it doesn't check if new files are created.

# -*- coding: utf-8 -*-
import os
import csv
import string

def touch(fname, times = None):
    with file(fname, 'a'):
        os.utime(fname, times)


for i in range(0, 939):
  with open('../data/maskFilenames.csv', 'rb') as f:
    mycsv = csv.reader(f)
    mycsv = list(mycsv)
    fname = string.strip(mycsv[i][1])
    touch(fname)
    print fname
