[CentralOH] cStringIO

[Joe Shaw]

Hi,

I'd probably also make use of contextlib.closing rather than managing the
file by itself.

with contextlib.closing(cStringIO.StringIO(s)) as f:
    # previous code here, no need to explicitly close() the file afterward

This ensures that the file is closed even in the case of error (and is,
IMO, cleaner than a try-finally block)
