मेरे पायथन 3 स्थापना मै मैक पर हूं, इसलिए मैक का डिफ़ॉल्ट 2.7 अजगर संस्करण भी है।

केवल जिस तरह से यह संभव है यदि आप पायथन 2 में हैं, तो पायथन 3 नहीं। आपके संदर्भ स्वरूपण को पायथन 2.7 में भी कार्यान्वित किया गया है, इसलिए यह बहुत संभावना है कि आप इसका उपयोग कर रहे हैं।

निश्चित, यह पता लगाने का एक बहुत आसान तरीका है: 

  import sys print (sys.version_info)

यदि आप पायथन 2 के साथ फंस रहे हैं, तो आप यह आपकी स्क्रिप्ट के शीर्ष पर सही विभाजन सक्षम करने के लिए रख सकता है: <__future__ आयात विभाजन से

c# - Highlight all words containing a letter in a richtextbox -

How do I highlight all the words in a letter in a rich text box? If I want to expose the words that contain the letters "a", such as a hat or candle word, both words are highlighted, I am using C # on Winform. Private Zero Button 208_Click (Object Sender, EventArgs E) {HighlightFrage (Rich Textbox 1, "A", Color. Yellow); } It exposes all the words with a word "a", but I'm not sure how to highlight the length of the spaces. Thank you. You can use the method to find incidents of sub-location. Then, use the property to change the colors back to Highlight colors for each event. int len ​​= richTextBox.TextLength; Int index = 0; String textconfind = "A"; // This will highlight the text you are viewing (index & lt; len) {richTextBox.Find (textToFind, index, len, RichTextBoxFinds.None); RichTextBox.SelectionBackColor = Color.Yellow; Index = rich textbox. Lesson Index (texttofind, index) + textaophind Langeline; } If you want...

Do you know about a problem due to Admob not being able to click on interstitial ads and therefore on Nexus 5 devices Have not brought any revenue? Fact: It does not have intermediate ads - some clickable, but mostly no . It comes with the old standalone Google Admob SDK and with the new Google Play Services SDK. It is on Nexus 5 with Android 4.4.2 , but it is possible that other devices are also affected. This happens in many programs in the Google Play Store - I'm not only with my application. For example, you can not Galaxy Nexus (Nexus 3), Galaxy S, on the HTC One. Below is a screenshot that opens the small info button in the clickable below the ad and OK, the Close X button also looks working properly , Though clicking on the ad does not happen - like it does not exist or something on it. Do you know of any solutions or possible solutions to the problem? Thanks! --- Update - - This activity declaration is: & amp; Activity Activity:...

I am trying to add a JTabbedPane to a panel, as well as for control I am using Migrates with the following buttons. However, I can not even get the JTabbedPane to fill without the buttons when they are not needed. The following SSCCE: public static zero main (string [] args) {jpn panel = new zpinal (new megallout (new lc.) Filling ())) ; Panel.add (new pocket ("+"); Panel.add (new pocket ("-"), "wrap"); Panel.ed (new zetaabbedpan (), "duration, increase"); Jeffre Frame = New Gefram (); Frame.add (panel); Frame.setSize (new dimension (300, 500)); Frame.setLocationRelativeTo (zero); Frame.setVisible (true); Frame.setDefaultCloseOperation (JFrame.EXIT_ON_CLOSE); } This creates a panel that looks like this: However, if I lack layout ( JPanel panel = new JPanel (new MigLayout)); ), looks like: If you do not want to apply a barrier to all the cells, do not say the layout ;-), instead, use the column and row barr...
