It's my impression that the readinto method does not fully support the buffer interface I was expecting. I've never had cause to use it until now. I've created a question on SO that describes my confusion:

Just use a memoryview and slice it:

b = bytearray(...) m = memoryview(b) n = f.readinto(m[some_offset:])

Also I saw some comments on "top-posting" am I guilty of this?

Kind of :)
