String <-> bytes encoding/decoding¶
- sage.cpython.string.bytes_to_str(b, encoding=None, errors=None)[source]¶
Convert
bytestostr.This decodes the given
bytesto a Python 3 unicodestrusing the specified encoding. It is a no-op onstrinput.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
>>> from sage.all import * >>> from sage.cpython.string import bytes_to_str >>> s = bytes_to_str(b'\xcf\x80') >>> s == u'π' True >>> bytes_to_str([]) Traceback (most recent call last): ... TypeError: expected bytes, list found
- sage.cpython.string.str_to_bytes(s, encoding=None, errors=None)[source]¶
Convert
strorunicodetobytes.It encodes the given
