The following inconsistency still bothers me, but I suppose it's an edge case that doesn't cause problems.
print r"hello world\"
File "<stdin>", line 1 print r"hello world\" ^ SyntaxError: EOL while scanning single-quoted string
In the first case, it's treated as a continuation character even though it's not at the end of a physical line. So it gives an error.
No, that is unrelated to line continuation. The \" is an escape sequence, therefore there is no double-quote to end the string literal.
Are you sure?
print r'\"'
\"
It's just a '\' here.
These are raw strings if you didn't notice.
It's all in the implementation. The tokenizer takes it as an escape sequence -- it doesn't specialcase raw strings -- the AST builder (parsestr() in ast.c) doesn't.
