Use:
csv.reader(*csvfile*, *dialect='excel'*,
***fmtparams*)¶<http://docs.python.org/2/library/csv.html#csv.reader>

This will allow you to iterate over the values, instead of reading them all
into memory at once.

csv.reader is documented at:

http://docs.python.org/3/library/csv.html

http://docs.python.org/2/library/csv.html
