[issue16546] ast.YieldFrom needlessly has its expr value as optional
Mark Dickinson added the comment: Brett: can you clarify---in what sense is the argument optional? I see that there's a doc issue at http://docs.python.org/dev/library/ast.html, where it's marked as optional but shouldn't but. Is there something more that's wrong? If you mean that ast.YieldFrom can be instantiated without an argument, isn't that the same for all the ast classes? ast.YieldFrom() _ast.YieldFrom object at 0x100760f50 ast.BoolOp() _ast.BoolOp object at 0x100760f90 -- nosy: +mark.dickinson ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue16546 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Brett Cannon added the comment: Where is the doc issue? And it's a bit more than just a doc issue anyway as Python.asdl has the same issue and that is what is used to generate the code that represents the nodes. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue16546 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Mark Dickinson added the comment: Ah, okay. I only looked at Grammar/Grammar, which looks fine. The doc issue is that at http://docs.python.org/dev/library/ast.html, under the heading 31.2.2. Abstract Grammar, it says: | Yield(expr? value) | YieldFrom(expr? value) But the docs insert the contents of Python.asdl directly, so you're right: it's not really a doc issue. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue16546 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

New submission from Brett Cannon: The grammar guarantees that 'yield from' statements have an expression to evaluate, plus a 'yield from' without an expression makes no sense. -- components: Library (Lib) messages: 176261 nosy: brett.cannon priority: normal severity: normal stage: test needed status: open title: ast.YieldFrom needlessly has its expr value as optional versions: Python 3.3, Python 3.4 ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue16546 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
