I'm trying to find the sum of all primes below 2 million in python -

- 

  ls = [] कुल = 0 i श्रेणी में (0,2000000): ls.append (i) के लिए श्रेणी में (2,2000000): श्रेणी में एक्स (2, इंट (फ्लोट (2000000 / i) +0.5): एलएस [इंट (फ्लोट (आई * x))] = 0 एलएस [1] = 0 जम्मू के लिए रेंज (0,2000000): कुल + = ls [j] प्रिंट कुल

यह कोड मुझे गलत जवाब दे रहा है। इसमें बड़ी संख्याएं शामिल हैं जो मुख्य नहीं हैं इसमें प्रधान संख्याओं की तुलना में 25 अधिक संख्याएं शामिल हैं।

आपका एल्गोरिदम गलत परिणाम दे रहा है, couldn ' आप समझते हैं कि आप किस दृष्टिकोण का इस्तेमाल करते हैं, अगर आप अधिक जानकारी दे सकते हैं तो बेहतर होगा।

प्रमुख संख्या को प्रभावी ढंग से उत्पन्न करने के लिए एरेथोथिनेस एल्गोरिदम के सिवे नामक एक एल्गोरिथ्म है एल्गोरिथ्म को एल्गोरिथ्म लिखने के विवरण के साथ समझाया गया है। 

  आयात करें गणित def प्रधानांक (एन): ए = श्रेणी (2, एन + 1) बी, सी = [], कुछ समय सी [0] को & lt; Math.sqrt (n): प्रथम एलेमेंट = सी [0] बी + = [प्रथम एलेमेंट] सी = [x के लिए एक्स में x यदि पहले% एलेमेंट! = 0] रिटर्न बी + सी टी = sum (प्राइमनल बेंज (2000000)) # यू गव प्रधान संख्या संख्या संख्याएं प्रिंट

apache - 504 Gateway Time-out The server didn't respond in time. How to fix it? -

Using a form submission on an embedded iframe , the customer downloads a compressed log file Requested. The request was sent to the server, which is the compressed log files, perform some database operations and returns a compressed file. After just 2 minutes, 504 gateway time-out server did not respond timely message on browser net panel How to fix this error? The log files were taking a long time to compress, and timeout was set to 2min The error was fixed by extending the file file: # # timeout: The number of seconds before getting the time out. # # # Timeout 120 timeout 600

c# - .net WebSocket: CloseOutputAsync vs CloseAsync -

-
We have a working ASP.NET Web API REST service, which is one of the methods of our controller, HTTPTTEX. .) Socket handler code looks something like this ... Public async task socket handler (AspNetWebSocketContext context) {_webSocket = context.WebSocket; ... while (! Cts.IsCancellationRequested) {WebSocketReceiveResult Results = _webSocket.ReceiveAsync (Input Segment, cts.Token) .Result; WebSocketsStateCollusocketState = _webSocket.State; If (result.MessageType == WebSocketMessageType.Close || currentSocketState == WebSocketState.CloseReceived) {// What should I use. CloseAysnc () or. CloseOutputAsync ()? _webSocket.CloseOutputAsync (WebSocketCloseStatus.NormalClosure, "Client Requested", cts.Token). Wait (); } If (currentSocketState == WebSocketState.Open) {...}}} .What is the difference between .CooseAsync () and CloseOutputAysnc ()? I tried both of them and they both seemed to work fine but some difference should be the same they both describe very similar to...

c++ - How to properly scale qgroupbox title with stylesheet for high resolution display? -

-
I am trying to apply a stylesheet for QGroupBox (QT4.8), which works on the normal screen ( 96 dpi) high resolution screen (Yoga 2 Pro, 3200x1800, 275 dpi, windows 8.1). The following style looks good on the 275 dpi screen, but the top margins on a regular 96 dpi screen are far too big. QGroupBox {border: 1px solid red; Range radius: 7px; Margin-top: 12x; } QGroupBox :: Title {subcontrol-origin: margin; Subcontrol-position: left above; Padding-left: 10px; Padding-right: 10px; } Changing the top-margin has an effect, but I did not get a proper setting which works on both screens. If I shorten the value, the content of the group box overlaps with the title on 275 dpi screen. I was also playing with units "East", "PX", "MX", "PT". Reading the document I would have guessed, "2 X" was the correct solution, which should be scaled with different screen resolutions. Without the stylesheet, the groupbox works well on both screens. ...
