#Here is the Python code you requested.

    """Register an individual resource record on a connected
    DNSServiceRef.
    Note that name conflicts occurring for records registered via this
    call must be handled by the client in the callback.
    sdRef:
    A DNSServiceRef returned by DNSServiceCreateConnection().
    flags:
    Possible values are kDNSServiceFlagsShared or
    kDNSServiceFlagsUnique.
    interfaceIndex:
    If non-zero, specifies the interface on which to register the
    record.  Passing kDNSServiceInterfaceIndexAny (0) causes the
    record to be registered on all interfaces.
    fullname:
    The full domain name of the resource record.
    rrtype:
    The numerical type of the resource record
    (e.g. kDNSServiceType_PTR, kDNSServiceType_SRV, etc.).
    rrclass:
    The class of the resource record (usually
    kDNSServiceClass_IN).
    rdata:
    A string containing the raw rdata, as it is to appear in the
    DNS record.
    ttl:
    The time to live of the resource record, in seconds.  Pass 0
    to use a default value.
    callBack:
    The function to be called when a result is found, or if the
    call asynchronously fails (e.g. because of a name conflict).
    Its signature should be
    callBack(sdRef, RecordRef, flags, errorCode).
    return value:
    A DNSRecordRef instance, which may be passed to
    DNSServiceUpdateRecord() or DNSServiceRemoveRecord().  (To
    deregister ALL records registered on a single connected
    DNSServiceRef and deallocate each of their corresponding
    DNSRecordRefs, close the DNSServiceRef.)
    Callback Parameters:
    sdRef:
    The connected DNSServiceRef returned by
    DNSServiceCreateConnection().
    RecordRef:
    The DNSRecordRef returned by DNSServiceRegisterRecord().
    flags:
    Currently unused, reserved for future use.
    errorCode:
    Will be kDNSServiceErr_NoError on success, otherwise will
    indicate the failure that occurred (including name conflicts).
    Other parameters are undefined if an error occurred.
