...bytes and bytearray implement the PEP 3118 buffer API. The bytes type only implements read-only requests; the bytearray type allows writable and data-locked requests as well. The element data type is always 'B' (i.e. unsigned byte). Constructors There are four forms of constructors, applicable to both bytes and bytearray: bytes(<bytes>), bytes(<bytearray>), bytearray(<bytes>), bytearray(<bytearray>): simple copying constructors, with the note that bytes(<bytes>...
...bytes object can be constructed at the Python scripting level by passing an int/long to the bytes constructor with the number of bytes to allocate. For example: b = bytes(100000) # alloc 100K bytes The constructor can also take another bytes object. This will be useful for the implementation of unpickling, and in converting a read-write bytes object into a read-only one. An optional second argument will be used to designate creation of a readonly bytes object. From the C API, the bytes obj...
...bytes in character strings. This would be a security risk if the bytes are security-critical when interpreted as characters on a target system, such as path name separators. For this reason, the PEP rejects smuggling bytes below 128. If the target system uses EBCDIC, such smuggled bytes may still be a security risk, allowing smuggling of e.g. square brackets or the backslash. Python currently does not support EBCDIC, so this should not be a problem in practice. Anybody porting Python to an EBCDI...
...bytes exclusively as the bytes are the canonical representation. Even if the encoding is "incorrect" by some standard, the file system will still map the bytes back to the file. Making use of this avoids the cost of decoding and reencoding, such that (theoretically, and only on POSIX), code such as this may be faster because of the use of b'.' compared to using '.': >>> for f in os.listdir(b'.'): ... os.stat(f) ... As a result, POSIX-focused library authors prefer to use bytes to ...
...bytes objects This PEP proposes that bytes and bytearray gain an optimised iterbytes method that produces length 1 bytes objects rather than integers: for x in data.iterbytes(): # x is a length 1 ``bytes`` object, rather than an integer For example: >>> tuple(b"ABC".iterbytes()) (b'A', b'B', b'C') Design discussion Why not rely on sequence repetition to create zero-initialised sequences? Zero-initialised sequences can be created via sequence repetition: >>> b'\x00'...
...bytes literals are subject to the same concatenation rules as adjacent string literals [3]. A bytes literal adjacent to a string literal is an error. Semantics Each evaluation of a bytes literal produces a new bytes object. The bytes in the new object are the bytes represented by the shortstringitem or longstringitem parts of the literal, in the same order. Rationale The proposed syntax provides a cleaner migration path from Python 2.x to Python 3000 for most code involving 8-bit strings. ...

...bytes values. If you do so, your code may work under Python 2, but it will not work properly under Python 3. For example, don't write somebytes == 'abc'. This will sometimes be true on Python 2 but it will never be true on Python 3, because a sequence of bytes never compares equal to a string under Python 3. Instead, always compare a bytes value with a bytes value, e.g. "somebytes == b'abc'". Code which does this is compatible with and works the same in Python 2.6, 2.7, and 3.1. The b in f...
