Removing blank lines while creating file

I have a script that creates files for each line of a CSV file. However, somehow a blank line is being added to the end of the newly created file.

Code:

 with open(fullCSV, 'r') as f:
            reader = csv.reader(f)
            csvList = list(reader)

        for item in csvList:
            if not os.path.exists(tempLoc + item[0]):
                os.mkdir(tempLoc + item[0])
            with open(tempLoc + item[0] + r"\prm.263", "w+") as f:
                csv.writer(f).writerow(item[1:])
            f.close

Is there some way I can strip the blank line on creation?

Thanks in advance
