import csv f = csv.reader(open('data.txt'), delimiter='\t') # 2GB text file sql = "INSERT INTO `data` VALUES (NULL,%s,%s,%s,%s,%s);" for row in f: print (sql, (row[0],row[1],row[2],row[3],row[4])) $ python3 parse.py3 > data.sql But because of print() being a function in Py3, print (sql, (row[0],row[1],row[2],row[3],row[4])) prints INSERT INTO `data` VALUES (NULL, '%s', '%s', '%s', '%s', '%s'); ('142', 'abcde', '2006-03-01 05:17:14', '', '') instead of INSERT INTO `data` VALUES (NULL, '142', 'abcde', '2006-03-01 05:17:14', '', ''); Anjanesh -- http://mail.python.org/mailman/listinfo/python-list
