socket

socket — Low-level networking interface

socket.makefile

When accessing socket as file:

• remember to call file.flush() after file.write()
• read() reads until EOF, so EOF for sockets means that connection is closed. Workarounds:
  • use \n at end of message and readline() for reading
  • use own framing protocol. I.e. Encode 32bit size on first 4 bytes (using struct). Then send data payload. On receiver side: read exactly 4 bytes and then N bytes specified in header.
• When file is in binary b mode, use str.encode() to convert strings into bytes
