From f2c1aa1661edb3e14ff8b7b9995f93e303c8acbb Mon Sep 17 00:00:00 2001 From: Victor Stinner Date: Tue, 26 Jan 2016 00:40:57 +0100 Subject: Add ast.Constant Issue #26146: Add a new kind of AST node: ast.Constant. It can be used by external AST optimizers, but the compiler does not emit directly such node. An optimizer can replace the following AST nodes with ast.Constant: * ast.NameConstant: None, False, True * ast.Num: int, float, complex * ast.Str: str * ast.Bytes: bytes * ast.Tuple if items are constants too: tuple * frozenset Update code to accept ast.Constant instead of ast.Num and/or ast.Str: * compiler * docstrings * ast.literal_eval() * Tools/parser/unparse.py --- Python/future.c | 5 ++++- 1 file changed, 4 insertions(+), 1 deletion(-) (limited to 'Python/future.c') diff --git a/Python/future.c b/Python/future.c index 163f87f673..75f210769e 100644 --- a/Python/future.c +++ b/Python/future.c @@ -79,7 +79,10 @@ future_parse(PyFutureFeatures *ff, mod_ty mod, PyObject *filename) i = 0; first = (stmt_ty)asdl_seq_GET(mod->v.Module.body, i); - if (first->kind == Expr_kind && first->v.Expr.value->kind == Str_kind) + if (first->kind == Expr_kind + && (first->v.Expr.value->kind == Str_kind + || (first->v.Expr.value->kind == Constant_kind + && PyUnicode_CheckExact(first->v.Expr.value->v.Constant.value)))) i++; -- cgit v1.2.1
