# This example illusatrates how binary data can be efficiently be passed

# between a bitarray object and an ndarray with dtype bool

#

import bitarray

import numpy

a = bitarray.bitarray('100011001001')

print a

# bitarray -> ndarray

b = numpy.fromstring(a.unpack(), dtype=bool)

print repr(b)

# ndarray -> bitarray

c = bitarray.bitarray()

c.pack(b.tostring())

assert a == c
