Guido van Rossum added the comment: FWIW, using class attributes to ensure __del__ does not hit AttributeError when __init__ failed is more idiomatic than using three-argument getattr().
The reason: in general it is possible that __del__ calls almost any other method on a class (e.g. for a buffered I.O stream open for writing, __del__ might call close() which might attempt to flush the buffer). It is not reasonable (and ugly :-) to use three-argument in all code that might be called by __del__. But it is reasonable to use class attributes to pre-initialize instance variables set by __init__ to "safe" defaults like None. ---------- nosy: +gvanrossum _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue12085> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
