array.array objects also have the writable buffer nature:

>>> import array
>>> b = array.array('c', '\0' * 10)
>>> b
array('c', '\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00')
>>> import struct
>>> struct.pack_into('<hhhh', b, 0, 1, 2, -1, -32768)
>>> b
array('c', '\x01\x00\x02\x00\xff\xff\x00\x80\x00\x00')

HTH,
