| .. _bytes-ops: | |
| Native bytes operations | |
| ======================== | |
| These ``bytes`` operations have fast, optimized implementations. Other | |
| bytes operations use generic implementations that are often slower. | |
| Construction | |
| ------------ | |
| * Bytes literal | |
| * ``bytes(x: list)`` | |
| Operators | |
| --------- | |
| * Concatenation (``b1 + b2``) | |
| * Indexing (``b[n]``) | |
| * Slicing (``b[n:m]``, ``b[n:]``, ``b[:m]``) | |
| * Comparisons (``==``, ``!=``) | |
| .. _bytes-methods: | |
| Methods | |
| ------- | |
| * ``b.decode()`` | |
| * ``b.decode(encoding: str)`` | |
| * ``b.decode(encoding: str, errors: str)`` | |
| * ``b.join(x: Iterable)`` | |
| .. note:: | |
| :ref:`str.encode() <str-methods>` is also optimized. | |
| Formatting | |
| ---------- | |
| A subset of % formatting operations are optimized (``b"..." % (...)``). | |
| Functions | |
| --------- | |
| * ``len(b: bytes)`` | |
| * ``ord(b: bytes)`` | |
