How to check updates of rpm packages

Hi,

is there an easy python way to check which of the two (or
more) versions of
a rpm package is newer ??

If I compare the version and release of the header
information I fail since
they return a string value. A comparison of let say
"9.12" and "9.7"
results not in the wanted behavior.

...

fdno_new = os.open(pak_new, os.O_RDONLY)
hdr_new = ts.hdrFromFdno(fdno_new)

fdno_old = os.open(pak_old, os.O_RDONLY)
hdr_old = ts.hdrFromFdno(fdno_old)

if hdr_new['release'] > hdr_old['release']:
   # install the newer version
else:
   # do nothing


Any ideas ??


Mit freundlichen Grüßen / Kind regards
