A class can bind attributes in __new__ and return a fully initialized object. If that’s perfectly ok, why doesn’t every class do everything in __new__, in which case there’s no reason for __init__ to exist at all?
If Python had been designed with the ability to subclass built-in immutable objects from the beginning, __init__ may well never have existed. I can't think of another language off the top of my head that splits the functionality of object creation in quite this way. C++ lets you override the 'new' operator, but that's strictly about allocating memory, it doesn't do any initialisation. -- Greg _______________________________________________ Python-ideas mailing list -- python-ideas@python.org To unsubscribe send an email to python-ideas-le...@python.org https://mail.python.org/mailman3/lists/python-ideas.python.org/ Message archived at https://mail.python.org/archives/list/python-ideas@python.org/message/TRTQ6M5GFGZLXH3IED6ICPQTUHEHFGRC/ Code of Conduct: http://python.org/psf/codeofconduct/
