For list comprehensions and generator expressions this is definitely a bug. But tuples syntax technically does not include surrounded parentheses. There is also a problem with generator expression passes as a single argument. Generator expression parentheses can be collapsed with function call parentheses: f(a for a in b). PR 10633 makes the following changes: * Fixes position for list comprehensions and generator expressions. * If generator expression parentheses are be collapsed with function call parentheses, the position of the AST node for the generator expression points to the left parenthesis. * For tuples surrounded with parentheses, the position of the AST node points to the left brace. For tuples without parentheses, it points to the position of the first tuple item. I am not sure whether these changes should be backported to maintained versions. ---------- nosy: +benjamin.peterson, brett.cannon, yselivanov _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue31241> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
