Python: Something like `map` that works on threads [closed]

Answer 1

I'd wrap it up in a function (untested):

import itertools
import threading
import urllib2
import Queue

def openurl(url, queue):
    def starter():
        try:
            result = urllib2.urlopen(url)
        except Ecxeption, exc:
            def raiser():
                raise exc
            queue.put((url, raiser))
        else:
            queue.put((url, lambda:result))
    threadind.Thread(target=starter).start()

myurls = ... # the list of urls
myqueue = Queue.Queue()

map(openurl, myurls, itertools.repeat(myqueue))

for each in myurls:
    url, getresult = queue.get()
    try:
        result = getresult()
    except Exception, exc:
        print 'exception raised:' + str(exc)
    else:
        # do stuff with result
