bytes_to_str
(b, encoding=None, errors=None)¶ Convert
bytes
tostr
.This decodes the given
bytes
to a Python 3 unicodestr
using the specified encoding. It is a no-op onstr
input.EXAMPLES:
sage: from sage.cpython.string import bytes_to_str sage: s = bytes_to_str(b'\xcf\x80') sage: s == u'π' True sage: bytes_to_str([]) Traceback (most recent call last): ... TypeError: expected bytes, list found
