The answer differs between Python 2 and 3. In Python 3 class C: # preferred in Python 3 pass and class C(object): pass are the same, so there is no point adding the explicit object inheritance. In Python 2 however class C: pass will create a "classic class" whereas class C(object): # preferred in Python 2 pass is a "newstyle class". The most notable difference between these is that properties work correctly only with newstyle classes. Therefore making all your classes "newstyle" is a good idea. > And while I am writing, what does OP stand for in this list?
