New submission from Serhiy Storchaka <storchaka+cpyt...@gmail.com>: Currently ast.literal_eval() accepts AST representing expressions like "+True" or "True+2j" if constants are represented as Constant. This is because the type of the value is tested with `isinstance(left, (int, float))` and since bool is a subclass of int it passes this test.
The proposed PR makes ast.literal_eval() using tests for exact type. I don't think it is worth backporting since it affects only passing AST to ast.literal_eval(). Usually ast.literal_eval() is used for evaluating strings. ---------- components: Library (Lib) messages: 312485 nosy: serhiy.storchaka priority: normal severity: normal status: open title: ast.literal_eval() shouldn't accept booleans as numbers in AST type: enhancement versions: Python 3.8 _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue32893> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
