Hi, I'm using the CSV module to parse a file usingwhitelistCSV_file = open("\\pathtoCSV\\whitelist.csv",'rb') whitelistCSV = csv.reader(whitelistCSV_file) for uname, dname, nname in whitelistCSV: print uname, dname, nname The first time I run the for loop the contents of the file is displayed. Subsequent attempts to run the for loop I don't get any data back and no exception.
That's because the csv reader object is an iterator. You're consuming it as you run through it. If you want to keep hold of the contents to run again (without reinitialising it) then pull the data into a list and iterate over that as many times as you like: data = list (whitelistCSV) for uname, dname, nname in data: # do stuff for uname, dname, nname in data: # do stuff again TJG -- http://mail.python.org/mailman/listinfo/python-list
