Thanks all. Yes csv module make it whole lot easier. I did try using it
before posting to list but couldn't get it working for some reason.
Steven, I updated the very last line of code as below, as I need to get the
word wrapped around quotes. Is that a good way of achieving that?
import csv
words = ["One", "Two", "Three, with comma", "Four 'with single quote'",
"Five"]
numbers = [1, 2, 3, 4, 5]
with open("c:/temp/test3.csv", "wb") as f:
writer = csv.writer(f)
writer.writerow(numbers)
writer.writerow(words)
writer.writerow([str(n) + " " + chr(34) + s + chr(34) for n, s in
zip(numbers, words)])
