But, as always, consistency is key, so try to stick to one of the above methods. So selection attribute PEP 8 outlines ways to allow statements to run over several lines. Some of these frameworks by convention use camel case and some use underscores. Does objective-c's method overhead make a 'many small methods' design approach inadvisable?
