 使用示例

from test import ThreadedWorker
from queue import Queue
 
urls_to_process = ["http://facebook.com", "http://pypix.com"]
 
work_queue = Queue()
result_queue = Queue()
 
def process_url(url):
  # TODO: Do some work with the url
  return url
 
def main():
  # spawn a pool of threads, and pass them queue instance 
  for i in range(5):
    t = ThreadedWorker(work_queue, result_queue, work_func=process_url)
    t.setDaemon(True)
    t.start()
 
  # populate queue with data  
  for url in urls_to_process:
    work_queue.put(url)
 
  # wait on the queue until everything has been processed   
  work_queue.join()
 
  # print results
  print(repr(result_queue))
 
main()
