This is unconventional and using eval is not SAFE too.
>>> s = 'qop="auth,auth-int,auth-conf",cipher="rc4-40,rc4-56,rc4,des,3des",maxbuf=1024,charset="utf-8",algorithm="md5-sess"'
>>> d = eval(' dict(%s)' % s)
>>> d.items()
[('algorithm', 'md5-sess'), ('maxbuf', 1024), ('charset', 'utf-8'),
('cipher', 'rc4-40,rc4-56,rc4,des,3des'), ('qop', 'auth,auth-int,auth-
conf')]
>>> for k,v in d.iteritems(): print k, '=', v
...
algorithm = md5-sess
maxbuf = 1024
charset = utf-8
cipher = rc4-40,rc4-56,rc4,des,3des
qop = auth,auth-int,auth-conf

For safe eval, take a look at http://aspn.activestate.com/ASPN/Cookbook/Python/Recipe/364469
