multithreading - python Queue get()/task_done() issue -

-

कतार के मेरे उपभोक्ता पक्ष: 

  m = queue.get () कतार कार्य_ऑन () & lt; बाकी प्रोग्राम & gt;

प्रश्न:

  1. क्या task_done () प्रभावी रूप से m कतार बंद पॉप करता है और कतार पर उपभोक्ता को जो भी ताला लगा है उसे रिलीज करना है?

  2. मुझे बाकी कार्यक्रम के दौरान m का उपयोग करना होगा क्या यह सुरक्षित है, या मुझे कॉल करने से पहले मुझे इसे कॉपी करने की आवश्यकता है task_done () ?

    3. P>

    नहीं, queue.get () कतार बंद आइटम चबूतरे ऐसा करने के बाद, आप जो भी चाहें कर सकते हैं, जब तक कि निर्माता इसे पसंद करता है और अब इसे स्पर्श नहीं करता। queue.task_done () को केवल कतार को सूचित करने के लिए कहा जाता है कि आप कुछ के साथ किया (यह विशिष्ट आइटम के बारे में भी नहीं पता है, यह कतार में अधूरा वस्तुओं की गणना करता है), ताकि < Code> queue.join () जानता है कि काम खत्म हो गया है।

Lists in scheme -

I am trying to write a function in the plan that takes every item list and class in the list, then returns the list As is (list xyz) . However, I'm not sure how to write a code that would do this. So far, I have (defined (category = list list) (cond [(empty? List) false) [and (list (SQL) (first A-list)) (Square-list) (The rest is a list)))]) but it returns to the list (cons y (cons z empty)) What can I do to return it to the list only in (list xyz) ? Thanks! You're almost there - make sure you type cons and List (The text book explains this section 13. You can find copies online). Conflict The first element for the 'rest' part and (usually) one (potentially empty) list as an example, (Opposition 1 blank) Number 1 as its first element and the empty list is in the form of 'rest' (Opposition 1 (Opposition 2 Empty)) No. 1 before Element, and (Opposition 2 empty) is in the form of 'rest'. List is just a simple shorth...

List View in C# -

I have a ListView in my C # and I want to select an item based on the number I give . Is it possible? Example: If my list adds, multiplied and divides as elements in the list, so if I give 2, then it has to be multiplied.
