In behavior carried over from Python 2 string literals, Python 3 byte string literals raise a less helpful ValueError exception when an invalid hex escape code is given:
>>> x = b'\x0'
ValueError: invalid \x escape
A string literal raises a SyntaxError and a full traceback including line number:
>>> x = '\x0'
File "<stdin>", line 1
SyntaxError: (unicode error) 'unicodeescape' codec can't decode
bytes in position 0-2: end of string in escape sequence

Here is a patch which include position number in the invalid bytes exception, wrap it into SyntaxError, and adds tests for bytes and strings. |
