Python 3.2 Release Python 3.2 Note: A newer security-fix release, 3.2.6, is currently available. Its use is recommended. Python 3.2 was released on February 20th, 2011. Python 3.2 is a continuation of the efforts to improve and stabilize the Python 3.x line. Since the final release of Python 2.7, the 2.x line will only receive bugfixes, and new features are developed for 3.x only. Since PEP 3003, the Moratorium on Language Changes, is in effect, there are no changes in Python's syntax and o...

...bits long. Therefore, when using this mode, the input and output strings must be a multiple of 'segment_size' bits in length. 'segment_size' must be an integer between 1 and block_size*8, inclusive. (The factor of 8 comes from 'block_size' being measured in bytes and not in bits). The default value for this parameter should be block_size*8. Implementors are allowed to constrain 'segment_size' to be a multiple of 8 for simplicity, but they're encouraged to support arbitrary values for general...

...bits for short ints. This will be changed to return a long int containing all the shifted-out bits, if returning a short int would lose bits (where changing sign is considered a special case of losing bits). Currently, hex and oct literals for short ints may specify negative values; for example 0xffffffff == -1 on a 32-bit machine. This will be changed to equal 0xffffffffL (2**32-1). Currently, the %u, %x, %X and %o string formatting operators and the hex() and oct() built-in functions behave ...

...bits set The actual top-most bit depends on existing uses for refcount bits, e.g. the sign bit or some GC uses. We will use the highest bit possible after consideration of existing uses. The refcount for immortal objects will be set to _Py_IMMORTAL_REFCNT (meaning the value will be halfway between _Py_IMMORTAL_BIT and the value at the next highest bit). However, to check if an object is immortal we will compare (bitwise-and) its refcount against just _Py_IMMORTAL_BIT. The difference means tha...
...bits, even though hash algorithm sizes are usually quoted in bits; MD5 is a 128-bit algorithm and not a 16-byte one, for example. This is because, in the sample code I looked at, the length in bytes is often needed (to seek ahead or behind in a file; to compute the length of an output string) while the length in bits is rarely used. Therefore, the burden will fall on the few people actually needing the size in bits, who will have to multiply digest_size by 8. It's been suggested that the update...
