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 (==, !=)

Methods

• b.decode()

• b.decode(encoding: str)

• b.decode(encoding: str, errors: str)

• b.join(x: Iterable)

Note

str.encode() is also optimized.

Formatting

A subset of % formatting operations are optimized (b"..." % (...)).

Functions

• len(b: bytes)

• ord(b: bytes)
