using bytearray with socket.recv_into

Question

I am doing some socket IO, and using a bytearray object as a buffer. I would like to receive data with an offset into this buffer using csock.recv_into as shown below in order

Answer 1

Use a memoryview to wrap your bytearray:

buf = bytearray(toread)
view = memoryview(buf)
while toread:
    nbytes = sock.recv_into(view, toread)
    view = view[nbytes:] # slicing views is cheap
    toread -= nbytes
