Some simple code is at ASPN: bit-field manipulation.ġ def bin( s): 2 return str( s) if s> 1) + str( s& 1)įrom "The Python Language Reference" page on the Data Model: Google Project Hostingīitstruct - This module performs conversions between Python values and C bit field structs represented as Python bytearrays. Python-bitstring - A Python module to help you manage your bits.
Apply operations in block groupings: ex: apply XOR 10101 (5 bits) repeatedly across a field.Ĭtypes - A foreign function library for Python - Python v2.7.3 documentation - part of the standard libraryīitarray - efficient arrays of booleans - C extension.Switch Endianness, with different block sizes.Similarly, revert regions of bits, apply logic to regions of bits, etc.That is, say: "rotate bits 13-17, wrapping around the edges," or, "rotate bits 13-17, lose bits on the one side, set all new bits to 0." Turn "11011000111101." into bytes, (padded left or right, 0 or 1,) and vice versa.Here is some information and goals related to Python bit manipulation, binary manipulation.
