Is there a good way in NumPy to convert from a bit string to a boolean array?

For example, if I have a 2-byte string s='\xfd\x32', I want to get a 16-length boolean array out of it.

Here's what I came up with:

A = fromstring(s, dtype=uint8) out = empty(A.size * 8, dtype=bool) for bit in range(0,8):  out[bit::8] = A&(1<<bit)

I just can't shake the feeling that there may be a better way to do this, though...

For short enough strings, it probably doesn't really matter. Any correct way will do. -- Robert Kern "I have come to believe that the whole world is an enigma, a harmless enigma that is made terrible by our own mad attempt to interpret it as though it had an underlying truth." -- Umberto Eco
