Victor Stinner f2c1aa1661 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

Eric V. Smith 1e5fcc3dea Fixed error creation if the problem is an empty expression in an f-string: use ast_error instead of PyErr_SetString. 2015-09-24 08:52:04 -04:00
Eric V. Smith 1d44c41b0c Move f-string compilation of the expression earlier, before the conversion character and format_spec are checked. This allows for error messages that more closely match what a user would expect. 2015-09-23 07:49:00 -04:00
