Victor Stinner 15a3095d64 compiler: don't emit SyntaxWarning on const stmt 
Issue #26204: the compiler doesn't emit SyntaxWarning warnings anymore when
constant statements are ignored.
 2016-02-08 22:45:06 +01:00
Victor Stinner a2724095cd compiler now ignores constant statements 
The compile ignores constant statements and emit a SyntaxWarning warning.

Don't emit the warning for string statement because triple quoted string is a
common syntax for multiline comments.

Don't emit the warning on ellipis neither: 'def f(): ...' is a legit syntax for
abstract functions.

Changes:

* test_ast: ignore SyntaxWarning when compiling test statements. Modify
  test_load_const() to use assignment expressions rather than constant
  expression.
* test_code: add more kinds of constant statements, ignore SyntaxWarning when
  testing that the compiler removes constant statements.
* test_grammar: ignore SyntaxWarning on the statement "1"

Victor Stinner f089196beb Simplify main() of test_ast 
* Use ast.parse() to get the AST for a statement
* Use str%args syntax for format a line

Issue #26204.

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
