[Twisted-Python] Newbie question

[Petr Mifek]

UGHHH, Thunderbird's syntax coloring sucks ;)

of course read that

result = "I'm the result"

Otherwise, look at:

http://twistedmatrix.com/documents/current/api/twisted.internet.interfaces.IReactorTime.html#callLater

especially look at the possible args and kwargs arguments and it'll give 
you a delayedCall:
