title: Why doesn't this queue work in multiprocessing?(append() method in function body)
body: <p>I am working to build a script with multiprocessing. 
  But while implementing the queue, I found out it doesn't work as I expected and still don't know why. </p>
  
  <p>Here is my pseudo code which consists of three parts:
  a function for making sentences list from strings, 
  strings list and outcome list for appending sentences,
  and the main code for implementing queue and multiprocessing.</p>
  
  <pre><code>def process_string(que_object):
  
      while que_object.empty():
         time.sleep(2)
  
      q = que_object.get(timeout=2)
      sentence = "Here is your string_"+q
      print(sentence)
      final_sentence.append(sentence)
  
  strings =["alskfj","alksjf"...]
  final_sentences = []
  
  if __name__ == "__main__":
  
      que_object = Queue()
      for i in strings:
          que_object.put(strings[strings.index(i)])
          #print(strings[strings.index(i)])
      #print(que_object)
  
      with Manager() as manager:
          L = manager.list(strings)
          process_list =[]
          for i in range(2):
              p = Process(target =process_string,args=(que_obejct,))
              process_list.append(p)
              p.start()
          for i in range(2):
  
              p.join()
              #time.sleep(1)
          print(final_sentences)
  </code></pre>
