यदि मैं एक फ़ाइल में प्रत्येक संख्या की संख्या की गिनती करना चाहता हूं, तो मैं इसे कैसे करने के लिए अजगर का उपयोग करूँ?

यह अनुराग उन्ियाल के उत्तर में वर्णित बिल्कुल सटीक एक ही एल्गोरिथ्म है, फाइल को readline () : 

  के बजाय इटरेटर के रूप में छोड़कर, संग्रह आयात डिफ़ॉल्ट से आज़माएं: IO आयात स्ट्रिंगियो # 2.6+, 3.x को छोड़कर आयात ईरर को छोड़कर: StringIO आयात से स्ट्रिंगआईओ # 2.5 डेटा = डिफॉल्ट डीआईसीटी (इंट) # ओपन के साथ ("फाइलनाम", "आर") एफ: # अगर स्ट्रिंगआईओ के साथ असली फाइल ("10 \ n5 \ n-1 \ n-1 \ n-1 \ n1 \ n1 \ n0 \ n2") च के रूप में: f में पंक्ति के लिए: डेटा [int (line)] + = 1 संख्या, संख्या में डेटा.iteritems (): प्रिंट संख्या, "पाया गया", गिनती, "समय"

Programming Language: C ++ Your Library: Qt Thanks. There is just one more correct answer than Paul Dixon, which answers your needs: / P > QClipboard * clipboard = QApplication :: clipboard (); CastString Selected Text = Clipboard-> Text (QClipboard :: Selection);

I have received a warning (or error may occur) that is given below Add Terminal Headers Here are 15 static components without a 15-futures end date * (no end) Http://www.example.com/video/css/global.css * (no time limit) http://www.example.com/video/js/global.js * (no expiration ) Http: //www.example.com/video/images/main-bg.png what it means and how to achieve it both in PHP and ASP.Net. I am on a shared hosting server, so please tell me some ways to use the code, because I can not make any modifications at the end of the server. If I expire the header, then there is no chance that if I make changes to the CSS, then the user will not be able to remove them immediately because CSS and other files have a fixed time limit (1 month, week ) Are cached for.

To make statistics automatically managed and honest, I would like to "update statistics", "create statistics" and There is no information about any management except "drop statistics" orders. In theory, UPDATE should handle the addition and removal of statistical data. In addition, I've never heard about the amount of storage or storage taking in large amounts, so I'm not sure whether there is any reason for the alarm or not. If you are seeing a potential problem, then I would suggest running an update before, if it does not clean it, it is leaving and then it appears to be safe operation (because it is the only query optimizer Is for). I will not leave "left" in the
