Ahem:
from twisted.internet import reactor
from twisted.internet.defer import inlineCallbacks
from twisted.web.client importt getPage
@inlineCallbacks
def fetchSequence(...):
homepage = yield getPage(homepage)
firstData = yield getPage(anotherPage)
if someCondition(firstData):
while:
secondData = yield getPage(wherever)
if someOtherCondition(secondData):
break
else:
...
So as I pointed out in another message in this thread, for several years it
has been possible to do this with Twisted. Since Python 2.5, you can do it
exactly as I have written above, which looks exactly the same as your example
code.
Is the only problem here that this style of development hasn't had been made
visible enough?
