`vars(obj)` is defined as returning `obj.__dict__` so technically it probably doesn't matter, but I feel that as a matter of aesthetics and future-proofing, we should avoid direct use of dunders whenever practical. Do you prefer to write `mylist.__len__()` over `len(mylist)`? Then you will probably prefer `obj.__dict__` over `vars(obj)` too :-) -- Steve _______________________________________________ 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/GNYDVF6VSXREPQJMQOG3CQARXAMT6MEQ/ Code of Conduct: http://python.org/psf/codeofconduct/
