Here's one on the Python website: http://search.live.com/results.aspx?q=python+bitvector&src=IE-SearchBox => http://pypi.python.org/pypi/BitVector/1.3 => http://cobweb.ecn.purdue.edu/~kak/dist/BitVector-1.3.html code=> http://cobweb.ecn.purdue.edu/~kak/dist/BitVector_1.3_CodeOnly.py.html "The bits of a bit array are stored in 16-bit unsigned ints." However, Python has variable size longs. Do you want something less elaborate? Here is what I think of when you say bitvector: bA= bitvector() bA[3]= 0 bA[7]= 1 bA[2].set() bA[1]^= b[9] bA[2:6].set() rangeA= ba[2:7] rangeA= "011101" rangeA.clear() bytearray is kind of close, but new in Py 3.0. How close is it to the perspective of the application you're writing? Here's some of it straight off the console: >>> b= bytearray(5) >>> b bytearray(b'\x00\x00\x00\x00\x00') >>> b[1]= 1 >>> b bytearray(b'\x00\x01\x00\x00\x00') >>> list(b) [0, 1, 0, 0, 0] -- http://mail.python.org/mailman/listinfo/python-list
