bitarray 0.7.0

This module provides an object type which efficiently represents an array of booleans. Bitarrays are sequence types and behave very much like usual lists. Eight bits are represented by one byte in a contiguous block of memory. The user can select between two representations; little-endian and big-endian. Most of the functionality is implemented in C. Methods for accessing the machine representation are provided. This can be useful when bit level access to binary files is required, such as portable bitmap image files (.pbm). Also, when dealing with compressed data which uses variable bit length encoding, you may find this module useful.<br /><br />Key features<br /><br /> . On 32bit machines, a bitarray object can contain up to 2^34 elements, that is 16 Gbits (on 64bit machines up to 2^63 elements in theory).<br /> . All crucial functionality implemented in C.<br /> . Bitarray objects behave very much like a list object, in particular slicing (including slice assignment and deletion) is supported.<br /> . The bit endianness can be specified for each bitarray object, see below.<br /> . Packing and unpacking to other binary data formats, e.g. numpy.ndarray, is possible.<br /> . Fast methods for encoding and decoding variable bit length prefix codes<br /> . Sequential search (as list or iterator)<br /> . Bitwise operations: &, |, ^, &=, |=, ^=, ~<br /> . Pickling and unpickling of bitarray objects possible.<br /> . Bitarray objects support the buffer protocol (Python 2.7 only)
