Python 线程池的实现

def main():
url_list = {"sina":"http://www.sina.com.cn",

#使用线程池
socket.setdefaulttimeout(10)
print 'start testing'
wm = WorkerManager(50)
for url_name in url_list.keys():
wm.add_job(do_get_con, url_name, url_list[url_name])
wm.wait_for_complete()
print 'end testing'

def do_get_con(url_name,url_link):
try:
fd = urllib2.urlopen(url_link)
data = fd.read()
f_hand = open("/tmp/ttt/%s" % url_name,"w")
f_hand.write(data)
f_hand.close()
except Exception,e:
pass

if __name__ == "__main__":
main()
