I'm trying to use the CSV module to read in some data and then use a
hashable method (as there are millions of records) to find unique ids
and push these out to another file,
You could either zip with a counter or use the uuid module,
depending on just how unique you want your ids to be.
<code>
import os, sys
import csv
import itertools
import uuid
stuff = "the quick brown fox jumps over the lazy dog".split ()
f = open ("output.csv", "wb")
writer = csv.writer (f)
#
# Style 1 - numeric counter
#
writer.writerows (zip (itertools.count (), stuff))
#
# Style 2 - uuid
#
writer.writerows ((uuid.uuid1 (), s) for s in stuff)
f.close ()
os.startfile ("output.csv")
</code>
