I wrote the below code

    headers = cleanHeaders(headers, method, body, host, port)
    for trial in range(10):
        try:
            if hasattr(http_conn, 'host'):
                conn = http_conn
            else:
                conn = http_conn(interface(host), port)
            conn._http_vsn_str = protocol
            conn._http_vsn = int(''.join([x for x in protocol if x.isdigit()]))
            if (sys.version_info < (2, 4)):
                def putheader(self, header, value):
                    if ((header == 'Accept-Encoding') and (value == 'identity')):
                        return
                    self.__class__.putheader(self, header, value)
                import new
                conn.putheader = new.instancemethod(putheader, conn, conn.__class__)
                conn.putrequest(method.upper(), url, skip_host=True)
            elif (not py3k):
                conn.putrequest(method.upper(), url, skip_host=True, skip_accept_encoding=True)
            else:
                import http.client
                def putrequest(self, method, url):
                    if (self._HTTPConnection__response and self._HTTPConnection__response.isclosed()):
                        self._HTTPConnection__response = None
                    if (self._HTTPConnection__state == http.client._CS_IDLE):
                        self._HTTPConnection__state = http.client._CS_REQ_STARTED
                    else:
                        raise http.client.CannotSendRequest()
                    self._method = method
                    if (not url):
                        url = ntob('/')
                    request = ntob('    ').join((method.encode('ASCII'), url, self._http_vsn_str.encode('ASCII')))
                    self._output(request)
                import types
                conn.putrequest = types.MethodType(putrequest, conn)
                conn.putrequest(method.upper(), url)
            for (key, value) in headers:
                conn.putheader(key, ntob(value, 'Latin-1'))
            conn.endheaders()
            if...

What's a good function header?

Here's a good function header?
