225+
226+ Get the string representation of *bytes *. This function is currently used to
227+ implement:meth: `!bytes.__repr__ ` in Python.
228+
229+ This function does not do type checking; it is undefined behavior to pass
230+ *bytes * as a non-bytes object or ``NULL ``.
231+
232+ If *smartquotes * is true, the representation will use a double-quoted string
233+ instead of single-quoted string when single-quotes are present in *bytes *.
234+ For example, the byte string ``'Python' `` would be represented as
235+ ``b"'Python'" `` when *smartquotes * is true, or ``b'\'Python\'' `` when it is
236+ false.
237+
238+ On success, this function returns a:term: `strong reference ` to a
239+ :class: `str ` object containing the representation. On failure, this
240+ returns ``NULL `` with an exception set.

244+
245+ Unescape a backslash-escaped string *s *. *s * must not be ``NULL ``.
246+ *len * must be the size of *s *.
247+
248+ *errors * must be one of ``"strict" ``, ``"replace" ``, or ``"ignore" ``. If
249+ *errors * is ``NULL ``, then ``"strict" `` is used by default.
250+
251+ On success, this function returns a:term: `strong reference ` to a Python
