[issue13224] Change str(x) to return only the qualname for some types

Guido van Rossum added the comment: Given Nick's feedback (and imagining what this would do to some codebases I know) I think this idea is dead, sadly. A helper function just doesn't give enough value, so let's not pursue that (it's easy to write the helper you want, it's hard to agree on what

[issue13224] Change str(x) to return only the qualname for some types

Vedran Čačić added the comment: getname sounds good, but is in fact very confusing. In most cases, what you'd actually want, and end up writing, is getname(type(x)), but we can't make it the default since for classes we would actually like x.__name__ directly. It seems you say the same with

[issue13224] Change str(x) to return only the qualname for some types

Nick Coghlan added the comment: That said, bringing over my overall comment from the PR review: I think the number of additional changes needed in the test suite and the standard library highlights the compatibility restoration busy-work risks of actually making this change: - while

Nick Coghlan added the comment: Specifically this message, where the unwritten rationale is to offer behavioural consistency across the builtin types that know their own name and include it in their current repr() output: https://mail.python.org/pipermail/python-ideas/2011-October/012464.html

[issue13224] Change str(x) to return only the qualname for some types

Guido van Rossum added the comment: For modules, __name__ is the fully-qualified name, and that's fine. But for classes and functions __name__ is just the "given name" from the syntax (whatever came after 'def' or 'class') and that's not fine -- for anything except builtins where we do this I

[issue13224] Change str(x) to return only the qualname for some types

Vedran Čačić added the comment: I'm very glad this is moving forward. Yes, types (classes) are most important, functions and modules not so much. The biggest use case for me is easier construction of sane error messages. In many cases, something like f'Got a {type(argument)}' should be

[issue13224] Change str(x) to return only the qualname for some types

Éric Araujo added the comment: I converted my patch to a PR. One use case mentioned on python-ideas was for reprs of PEP 384 types; need to hunt down where typing could benefit from the new str(class). The quote in my first message mentions printing err.__class__ rather than

Martin Panter added the comment: I’m a bit confused. In the current patch, the new type_str() function appears to use the “qualname” (which I support), but some of the test changes seem to contradict this, e.g.: C.foo(1) -classmethod class 'test.test_descrtut.C' 1 +classmethod C 1 Also, I
