Traceback (most recent call last):
  File "client.py", line 10, in <module>
    conn.send(b'')
  File "/usr/lib/python3.6/ssl.py", line 941, in send

  File "/usr/lib/python3.6/ssl.py", line 642, in write
    return self._sslobj.write(data)
ssl.SSLEOFError: EOF occurred in violation of protocol (_ssl.c:2074)

This error is not what I expected. I expected a noop instead.

My guess is, that python calls SSL_write (3.6 branch, _ssl.c:2038) with that empty buffer.
The manpage states: "When calling SSL_write() with num=0 bytes to be sent the behaviour is undefined."

This undefined behaviour should either be documented in python, or defined to either raise an exception (ValueError?) or defined as a noop. I'd prefer the latter.
