1"""This module tests SyntaxErrors.2Here's an example of the sort of thing that is tested.3>>> def f(x):4... global x5Traceback (most recent call last):6SyntaxError: name 'x' is local and global7The tests are all raise SyntaxErrors. They were created by checking8each C call that raises SyntaxError. There are several modules that9raise these exceptions-- ast.c, compile.c, future.c, pythonrun.c, and10symtable.c.11The parser itself outlaws a lot of invalid syntax. None of these12errors are tested here at the moment. We should add some tests; since13there are infinitely many programs with invalid syntax, we would need14to be judicious in selecting some.15The compiler generates a synthetic module name for code executed by16doctest. Since all the code comes from the same module, a suffix like17[1] is appended to the module name, As a consequence, changing the18order of tests in this module means renumbering all the errors after19it. (Maybe we should enable the ellipsis option for these tests.)20In ast.c, syntax errors are raised by calling ast_error().21Errors from set_context():22TODO(jhylton): "assignment to None" is inconsistent with other messages23>>> obj.None = 124Traceback (most recent call last):25SyntaxError: assignment to None (<doctest test.test_syntax[1]>, line 1)26>>> None = 127Traceback (most recent call last):28SyntaxError: assignment to None (<doctest test.test_syntax[2]>, line 1)29It's a syntax error to assign to the empty tuple.

1r"""Test correct treatment of various string literals by the parser.2There are four types of string literals:3 'abc' -- normal str4 r'abc' -- raw str5 b'xyz' -- normal bytes6 br'xyz' | rb'xyz' -- raw bytes7The difference between normal and raw strings is of course that in a8raw string, \ escapes (while still used to determine the end of the9literal) are not interpreted, so that r'\x00' contains four10characters: a backslash, an x, and two zeros; while '\x00' contains a11single character (code point zero).12The tricky thing is what should happen when non-ASCII bytes are used13inside literals. For bytes literals, this is considered illegal. But14for str literals, those bytes are supposed to be decoded using the15encoding declared for the file (UTF-8 by default).16We have to test this with various file encodings. We also test it with17exec()/eval(), which uses a different code path.18This file is really about correct treatment of encodings and19backslashes. It doesn't concern itself with issues like single20vs. double quotes or singly- vs. triply-quoted strings: that's dealt21with elsewhere (I assume).22"""23import os24import sys25import shutil26import
