#Here is the Python code you requested.

    """Resolve a service name discovered via DNSServiceBrowse() to a
    target host name, port number, and txt record.
    Note: Applications should NOT use DNSServiceResolve() solely for
    txt record monitoring; use DNSServiceQueryRecord() instead, as it
    is more efficient for this task.
    Note: When the desired results have been returned, the client MUST
    terminate the resolve by closing the returned DNSServiceRef.
    Note: DNSServiceResolve() behaves correctly for typical services
    that have a single SRV record and a single TXT record.  To resolve
    non-standard services with multiple SRV or TXT records,
    DNSServiceQueryRecord() should be used.
    flags:
    Currently ignored, reserved for future use.
    interfaceIndex:
    The interface on which to resolve the service.  If this
    resolve call is as a result of a currently active
    DNSServiceBrowse() operation, then the interfaceIndex should
    be the index reported in the browse callback.  If this resolve
    call is using information previously saved (e.g. in a
    preference file) for later use, then use
    kDNSServiceInterfaceIndexAny (0), because the desired service
    may now be reachable via a different physical interface.
    name:
    The name of the service instance to be resolved, as reported
    to the DNSServiceBrowse() callback.
    regtype:
    The type of the service instance to be resolved, as reported
    to the DNSServiceBrowse() callback.
    domain:
    The domain of the service instance to be resolved, as reported
    to the DNSServiceBrowse() callback.
    callBack:
    The function to be called when a result is found, or if the
    call asynchronously fails.  Its signature should be
    callBack(sdRef, flags, interfaceIndex, errorCode, fullname,
    hosttarget, port, txtRecord).
    return value:
    A DNSServiceRef instance.  The resolve operation will run
    indefinitely until the client terminates it by closing the
    DNSServiceRef.

    sdRef:
