BitVector A pure-Python memory-efficient packed representation for bit arrays This class presents a pure-Python memory efficient packed representation for bit arrays. In version 1.4.1, the reset() method now returns 'self' to allow for cascaded inovocation with the slicing operator. This version also removes the discrepancy between the value of the __copyright__ variable in the module and the value of license variable in setup.py. Version 1.4 supports slice assignment and a reset method that allows a previously constructed bit vector to be reinitialized to all 0's or all 1's. The code was also cleaned up with pychecker for this version. The class supports the following operators/methods: __getitem__ __setitem__ __len__ __getslice__ __str__ __iter__ __contains__ __int__ __add__ __eq__, __ne__, __lt__, __le__, __gt__, __ge__ '|' for bitwise or '&' for bitwise and '^' for bitwise xor '~' for bitwise inversion '<<' for circular shift to the left '>>' for circular shift to the right '+' for concatenation intValue(), __int__ for returning the integer value divide_into_two permute unpermute pad_from_left pad_from_right read_bits_from_file write_to_file read_bits_from_fileobject write_bits_to_fileobject slice assignment reset http://RVL4.ecn.purdue.edu/~kak/dist/BitVector-1.4.1.tar.gz?download Avinash Kak 213cccecbaade86f6ca482f75cb1dfbfe21d98cb 1.4.1
