Hi, I have a few classes that manipulate documents. One is really a process that I use a class for just to bundle a bunch of functions together (and to keep my call signatures the same for each of my manipulator classes).
So my question is whether it's bad practice to set things up so each method operates on self.document or should I pass document around from one function to the next? pseudo code: class ManipulatorA(object): def process(self, document): document = self.do_one_thing(document) document = self.do_another_thing(document) # bunch of similar lines return document or class ManipulatorA(object): def process(self, document): self.document = document self.do_one_thing() # operates on self.document self.do_another_thing() # bunch of similar lines return self.document I ask because I've been told that the first case is easier to understand. I never thought of it before, so I'd appreciate any comments. thanks, --Tim -- http://mail.python.org/mailman/listinfo/python-list
