Given a Python string describing object.attribute, how do I separate the attributes's namespace from the attribute?

Assuming that the namespace is always alphanumeric, you could first split on /[^a-zA-Z.]/, then rsplit on .:

>>> import re
>>> ns_attr_split = lambda s: re.split("[^a-zA-Z.]", s,
1)[0].rsplit('.')
>>> ns_attr_split("obj.dict['key.word']") 
['obj', 'dict']

Obviously this isn't exactly what you want… but the fiddling would be straight forward.
