Oups, thanks Daniel, I missed that method in the documentation :
c0.get_as_chain().get_id()
does the trick.
I still have a question concerning the nice way for retrieving attribute Keys
>> 3. Is there a nicer way to get a keyType for instance from its string ? In my example, I retrieved chainKey as the third element of the integer keys list returned by get_int_attributes(), this is not very satisfying, and I thought of resorting to a function such as : >> >> def getChainKey( chain ): >> for k in chain.get_int_attributes() : >> if k.get_string() == 'chain' : >> return k >> return None >> >> Still, I wonder if there is an IMP mechanism I am not aware of, that I should prefer instead.
