At least for the examples of buffers that I've seen, using the buffer interface for objects that support it is equivalent to automatically applying str() to them. This is, strictly speaking, an optimization. >>> a = array.array("i", [1, 2, 3]) >>> str(a) "array('i', [1, 2, 3])" >>> str(buffer(a)) '\x01\x00\x00\x00\x02\x00\x00\x00\x03\x00\x00\x00'

str(buffer(u"abc")) 'a\x00\x00\x00b\x00\x00\x00c\x00\x00\x00'
