The socket must be connected to a remote socket. This method continues
to send data from data until either all data has been sent or an
error occurs. None is returned on success. On error, an exception is
raised, and there is no way to determine how much data, if any, was
successfully processed by the receiving end of the connection.
This method is a coroutine.

The address must be already resolved to avoid the trap of hanging the
entire event loop when the address requires doing a DNS lookup. For
example, it must be an IP address, not an hostname, for AF_INET and
AF_INET6 address families. Use getaddrinfo() to resolve the hostname
asynchronously.
