A general description of my issue. To my understand, python's feature such as "name-reference-object" and "garbage collection" system did some of work for you, it makes your life easier, but you still need to add your explicit application in your code.
For example, Composition implementation: you may need to do 5 job with C++, but only 2 job with python, the other 3 job is done by python implicitly. association implementation: You need 3 job with C++, but 1 with python. it seems python's object's lifecycle handling has reached this level, all you should do is just "associating and de-association". Here is exactly of my question, for composition, the best code may be you do 2 job explicitly, 3 job done by python implicitly. Code_Zero. 1 job(by you) + 4(by python) does NOT work. Code_one. 2 job(by you) + 3(by python) works. That is the best one. Code_two. 3 job( by you) + 2 (by python) works too, Code_three. 4 job(by you) + 1(by python) works too. Since i am not familiar with python yet, my code most likely would gets into Code_two or Code_three(Code_Zero is also possible for new guys like me), though they also work, they are bad code. What i am looking for is the Code_one example, i thought many OOP application designer may have met this issue, so a good Code_one reference is the best choice to start this project. 2011/11/11 Jerry Zhang <jerry.scofi...@gmail.com> > > > 2011/11/11 Chris Angelico <ros...@gmail.com> > >> On Fri, Nov 11, 2011 at 10:14 AM, Chris Kaynor <ckay...@zindagigames.com> >> wrote: >> > Continuing this OT discussion, would it be a brain transplant, or a >> > full body transplant? >> >> It's just a rebinding.
