Is there something similar to ?: operator (C/C++) in Python?

Unless the obj_i_a and obj_i_b are totally unrelated (very unlikely), I
think this might/should be refactored so that the decision between each
obj_i_a and obj_i_b is done in a separate obj_i_factory callable. If
you provide an example or two of specific triples (type_of_obj_i,
obj_i_a, obj_i_b), we'll have a better idea of whether factories are an
overkill in this case or not.
