I am using in my python scripts the following in order to find the host name

import socket
host = socket.gethostname()

or

local_fqdn = socket.getfqdn(socket.gethostname())

etc

the question is if its necessary to close the socket after above code?

as

s.shutdown(socket.SHUT_RDWR)
s.close()

or

    if socket_:
        socket_.close()
