* A backslash-character pair that is not a valid escape sequence now generates
a :exc:`SyntaxWarning`, instead of :exc:`DeprecationWarning`.
For example, ``re.compile("\d+\.\d+")`` now emits a :exc:`SyntaxWarning`
(``"\d"`` is an invalid escape sequence), use raw strings for regular
expression: ``re.compile(r"\d+\.\d+")``.
(``"\d"`` is an invalid escape sequence, use raw strings for regular
expression: ``re.compile(r"\d+\.\d+")``).
In a future Python version, :exc:`SyntaxError` will eventually be raised,
instead of :exc:`SyntaxWarning`.
