Hi Samuel, Classes already have a `obj.mro()` public method that wraps their private dunder `__mro__`. Non-classes (instances) don't have a `__mro__`. > Additionally, the class named `object` should have a method named > `__mro__` and any class which inherits from `object` may override > `__mro__` or inherit the default `object.__mro__`. Guido's time machine strikes again. This has existed since Python 2.2 or thereabouts, so more than twenty years ago: >>> object.__mro__ (,) >>> object.mro() [] -- 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/ZYGLKVXQKWJX3KHNZGIJRGRXJBJBGIP4/ Code of Conduct: http://python.org/psf/codeofconduct/
[Python-ideas] An interface for `mro` methods similar to the interface for `iter`, `getattr`, etc...
*Greetings Fellow Earthlings,*
*In python 3.11, python has a number of built-in functions which act as an
Interface for magic dunder methods. Two examples of what I am talking about
are shown below: *
*Begin Example 1 of 2*
*rocky = object()x = getattr(rocky, "length") x = rocky.__getattr__("length") *
*Begin Example 2 of 2*
*box = [1, 2, 3]it = iter(box) it = box.__iter__()*
*My suggestion is that in future versions of python, we will have `mro()`
behave in a similar fashion. *
*obj = object()x = mro(obj) x = obj.__mro__() *
*Additionally, the class named `object` should have a method named
`__mro__` and any class which inherits from `object` may override
`__mro__` or inherit the default `* *object* *.__mro__` . *
