implicit conversion - Dedicated Scala String interpolation -

दिए गए नक्शा स्थिरांक के लिए 

  val ctt = मैप ("ए" -> 1) "<">        
  c "a"   
 उद्धार करता है  सूची (1) ?  
  नोट   
  सी "a, b" res: सूची (1, 2) सी "ए, बी" रिज़ः सूची (1,2) सी "ए, डब्ल्यू" रिज़ः सूची (1) सी "डब्ल्यू" रिज़ः सूची ()    < P> 
 
 निम्न कार्य करता है:  
  scala & gt; वैल सीटीटी = नक्शा ("ए" - & gt; 1, 'बी' - & gt; 2) सीटीटी: स्कला। कोलिन्शन.इमट्यूबल। मैप [स्ट्रिंग, इंट] = नक्शा (ए -> 1, बी - & gt; 2) स्केला & gt; अंतर्निहित वर्ग CttHelper (val sc: StringContext) AnyVal तक फैलता है {| Def c (आर्ग्स: कोई *): Int = ctt (sc.parts.head) | } परिभाषित वर्ग CttHelper scala & gt; सी "ए" res0: Int = 1   
 या अपने अद्यतन संस्करण के लिए:  
  अंतर्निहित वर्ग CttHelper (val sc: StringContext) AnyVal {def c (आर्ग्स: कोई *): सूची [इंट] = sc.parts.head.split (',')। नक्शा (_। ट्रिम) .toList.flatMap (ctt.get)}   < P> और फिर:  
  स्कला & gt; C "a, w" res5: सूची [int] = सूची (1) स्केल & gt; सी "ए, बी" रिज 6: सूची [इंट] = सूची (1, 2) स्केल & gt; सी "ए, बी" रिज 7: सूची [इंट] = सूची (1, 2) स्केल & gt; C "a, w" res8: सूची [इंट] = सूची (1) स्केल & gt; C "w" res9: सूची [इंट] = सूची ()   
 आप शायद यह जांचना चाहते हैं कि  sc.parts  में एक तत्व है, हालांकि, जब तक कि आप वास्तव में इंटरपोलेटेड चर के साथ कुछ करना चाहते हैं।

python - Receiving "KeyError" after decoding json result from url -

-
I am new to Python I am trying to parse JSON result from a URL. Basically, I was using the following: response = urllib.request.urlopen (url) json_obj = json.load (response) It should be a stroke "str 'not' bytes' in the lines of a given" JSON object, so after searching on the StackoverView Flo, I decode the response in this way: F = urllib.request.urlopen (Url) charset = f.info (). Get_param ('charset', 'utf8') data = f.read () decoded = json.loads (data.decode (charset)) If I print "decode" I is as follows: { 'link': { 'summary data': 'https: // localhost / piwebapi / streams / p0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTExNQU42NDIwXFNJTlVTT0lE / summary' 'value': 'https: // localhost / Piwebapi / streams / P0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTExNQU42NDIwXFNJTlVTT0lE / price ',' InterpolatedData ':' https: // localhost / Piwebapi / streams / P0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTE...

javascript - How to ignore requestAnimationFrame in browsers which don't support it -

-
Assume that we have a feature / module, which increases a website so it is not really necessary and it I use the requestAnimationFrame , which is like IE8 / 9, I could have polyphil requestAnimationFrame , but because it is only an increase, the old browser should ignore it. The code of this module looks more or less like this: ; {Function (window, document, undefined) {'strict use'; // example module // constructor function module, option) {// ...} Module.prototype = {init: function () {// if requestAnimationFrame Not supported, a warning warning ("init") should be popped up;}, method: function () {/ if the request animationfreck is not supported, then alert any warning ("Start");}}; Window.Module = Module;} (window, document) should pop up; Then I can create a new example var example = new module (document.getElementById ('test')); and "interact with" instance.init (); Instance.method (); The problem with this code ...
