[python]파이썬 2의 보수, bitstring 모듈 예시

Two's Complement in Python

It's not built in, but if you want unusual length numbers then you could use the bitstring module.

>>> from bitstring import Bits
>>> a = Bits(bin='111111111111')
>>> a.int
-1

The same object can equivalently be created in several ways, including

>>> b = Bits(int=-1, length=12)

It just behaves like a string of bits of arbitrary length, and uses properties to get different interpretations:

>>> print a.int, a.uint, a.bin, a.hex, a.oct
-1 4095 111111111111 fff 7777
