[Twisted-Python] script can be used as namespace?

Dec. 31, 2006

      I am working on an example:

from twisted.internet.app import Application
from twisted.internet.protocol import Protocol, Factory

class Fibonacci(Protocol):
    """Serve a sequence of Fibonacci numbers to all requesters"""

def dataReceived(self, data):
        self.factory.new
 = self.factory.a + self.factory.b
        self.transport.write('%d' % self.factory.new)
        self.factory.a = self.factory.b

self.factory.b = self.factory.new

def main():
    import fib_server    # Use script as namespace

    f = Factory()
    f.protocol = fib_server.Fibonacci
    f.a, f.b = 1, 1
    application = Application("Fibonacci")

    application.listenTCP(8888, f)
    application.save()

if'__main__' == __name__:

    main()

I have questions as the following:

   1. Is application.save( ) that make Fibonacci.tap file?
    2. testing on "twistd -f Fibonacci.tap" got message "Failed to load
   application: No module named fib_server".Can we use script as namesp?
