| .. _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]``) |
| * Repetition (``b * n``, ``n * b``) |
| * Comparisons (``==``, ``!=``) |
| |
| .. _bytes-methods: |
| |
| Methods |
| ------- |
| |
| * ``b.decode()`` |
| * ``b.decode(encoding: str)`` |
| * ``b.decode(encoding: str, errors: str)`` |
| * ``b1.endswith(b2: bytes)`` |
| * ``b.join(x: Iterable)`` |
| * ``b1.startswith(b2: bytes)`` |
| * ``b.translate(table: bytes)`` |
| |
| .. 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)`` |
