[AstroPy] Capturing pyfits warnings

[Bridgman, William T.]

I'm trying to get an inventory of all the FITS files I'm storing  
locally, to track down duplicates and determine data gaps in covering  
certain phenomena.

I'm getting a warning from pyfits about file size mismatches.  Is  
there an elegant way to capture this message, or a warning code, that  
I can save with the file inventory record for generating a summary  
report?

I see some items in the pyfits doc on capturing this with the warnings  
module but it seems more focussed on logging.  It is unclear how I  
would capture the warning information as a separate variable to save  
with the inventory dictionary.

Thanks,
Tom
