Sorting two layers array by underscore .sortBy or javascript .sort function -

-

मुझे JSON सॉर्टिंग में वृद्धि के साथ समस्या है अब यह देखा गया: 

  var array = {"2014/2015": {"gamesplayed": 17, "लक्ष्य": 2, "सहायता": 8, "अंक": 10} , "2013/2014": {"गेम्सप्लेड": 52, "लक्ष्य": 18, "सहायता": 16, "अंक": 34}, "2012/2013": {"गेम्सपेलेड": 39, "लक्ष्य ": 12," सहायता ": 15," अंक ": 27}};

मुझे वर्षानुसार आइटम सॉर्ट करने और 2012-2013 जैसी वस्तुएं प्राप्त करने की आवश्यकता है: {...}, 2013/2014: {...}, 2014/2015: {.. ।} मैं इसे सॉर्ट करने का प्रयास करता हूं: 

  var sorted = array.sort (फ़ंक्शन (a, b) {return a - b;});

लेकिन यह कंसोल में गलत तरीके से दिखाती है।

आपका सरणी चर वास्तव में एक ऑब्जेक्ट है, जिसके पास कोई .sort () विधि नहीं है, चूंकि चाबियाँ अनारडेड हैं।

class - Kivy: how to instantiate a dynamic classes in python -

Using KV lang on my Python code, I have taken a hard time trying to instantiate a dynamic class, the following Consider the code: My test.kv file looks like this: & lt; MyPopup @ popup: Title: 'Hello' size_hunt: (1, .6) Grid layout: ID: RouteGrid column: 2 padding: ['8dp', '4dp', '8dp', '4dp'] Difference: '8dp' label: text: 'some text here' button: text: 'OK' On_press: do_something () & lt; MyGrid & gt;: Rows: 1 Button: Text: 'Show Popup' on_press: root.pop.show () Then import Kivy.app into my test.py: I get the following error: raise Factory Exception ('Uncount Class' '% name) kivy.factory.FactoryException: Unknown class Can anyone tell me how to do this properly, what do I remember? If you need more information please let me know Thank you. Takes a call to the factory before the KV file is loaded, so you want the class to Are not yet in existence. As long as no clas...

python - mayavi mapping a discrete colorbar on a surface -

I want to change the color of the surface on the basis of another value (an ID) that is considered discrete (hence I In the simplified example given below, I have prepared a field with 3 different IDs: 0 / red on left 2 / blue 1 / green left But with the code below, I have some strange behavior on the border between red and blue (green Point) I think this is probably due to an interpolation! Code: import from import mlab np # np # my dataset -simplified-x, y, z = np.mgrid [-3: 3: 100] H, -3: 3: 100h, -3: 3: 100 h] value = NP. SQLT (x ** 2 + y ** 2 + z ** 2) # My color value: Volume is divided into 3 sub-versions taking colorvalues ​​with X = np.empty (values.shape) colorvalues [0:33,:,:] = 0 colorvalues ​​[33:66,:,:] = 2. Look [66:,:,:] = 1 src = mlab.pipeline.scalar_field (value) src.image_data.point_data.add_array (colorvalues.T.ravel ()) (1) .name = 'MyID' src.image_data. point_data.update src.image_data.point_data.get_array () # surface, contour = mlab.pipe...
