I like something like:
class Constants(object):
def __init__(self, **kw):
for name, val in kw.iteritems():
setattr(self, name, val)
Then:
opAssoc = Constants(RIGHT=0, LEFT=1)

fileusage = Constants(Transcript=1, TextMode=2)
filemode = Constants(Read=1, Write=2, Append=4)
filemode.WriteAppend = filemode.Write | filemode.Append
class Constants then becomes a nice place to define methods
to convert values to associated names for debugging and such.
