Hello and thanks for your time.

Regards,

I've already written this some times:

d1.addCallback(5, reactor.callLater, d2.callback, "firelater")

Hope this, helps,

Dear list,

I would like to add a callback that delays the chain. In other words I would like to combine: defer.Deferred().addCallback and reactor.callLater

The only solution I came up with was the code below.

There must be a more elegant way to do this. Any ideas would be greatly appreciated, All the best,

*************************begin from twisted.internet import reactor, defer

def printResults(results, arg): print "In printResults results=", results print "In printResults arg=", arg if arg == 2: reactor.stop()

def fireLater(results, d2): print "In fireLater results=", results reactor.callLater(5, d2.callback, "firelater")

d1 = defer.Deferred() d2 = defer.Deferred() d2.addCallback( printResults, 1) d2.addCallback( printResults, 2)

d1.addCallback(fireLater, d2) d1.callback("fire")

reactor.run() *************************end
