Finding closest values in a list of dictionary keys Python -


एक बिंदु को देखते हुए: 

  a = [X, Y, Z]

मैं अनिवार्य रूप से शब्दकोशों की एक सूची से उस बिंदु तक निकटतम 3 बिंदु ढूंढने की कोशिश कर रहा हूं।

यह जिस प्रकार की डेटा की तुलना करने की आवश्यकता है, उसका एक सरल उदाहरण दिया गया है रूप में: 

  अंक = [{'बिंदु': 1, 'समनुरूप': [0,1,2]}, {'प्वाइंट': 2 ', सह-समन्वय ': [0,1,3]}, {' बिंदु ': 3,' समांतर ': [1,1,2]}] आदि।

कोई भी विचार या सुझाव

आप एक रिवर्स लुकअप टेबल रख सकते हैं, जहां आप कुंजी-वैल्यू युग्म वापस करते हैं और निर्देशांकों को संग्रहीत करते हैं कुंजी के रूप में यह कार्यान्वयन करना आसान है फिर आप फिर से कुंजियाँ वापस कर सकते हैं और प्रत्येक निर्देशांक पर दूरी सूत्र कर सकते हैं।

जैसा कि आप जानते हैं, दूरी सूत्र है: 

  dist = sqrt ((x1 - x2) ** 2 + (y1 - y2) ** 2 + (z1 - z2) ** 2)

नोट: ऐसा लगता है कि आपके पास उस सूची में 3 अलग-अलग शब्दकोश हैं।

ios - How do I use CFArrayRef in Swift? -

I am using Objective-class in my Swift Project through a bridging header. The method signature looks like this: - Some cement (some type) some parameters; I started by getting an example of class, calling method, and storing the value: var myInstance = MyClassWithThatMethod (); Var cfArr = myInstance.someMethod (some value); Then try to get the value in the array: var valueInArrayThatIWant = CFArrayGetValueAtIndex (cfArr, 0); However, I get the error unmanaged & lt; Cfarray & gt; Not like 'CFArray' . Unmanaged & lt; Cfarray & gt; also means? I looked, but I do not need to change the array in a fast array (though it would be good). I need to be able to get value from the array. I also tried CFArray method to pass in a function: func doSomeStuffOnArray (myArray: NSArray) {} Although I get the same error when using: doSomeStuffOnArray (cfArr); // unmanaged & lt; CFArray & gt; I am using CFArray because I want to sto...

scala - Play Framework - how to bind form to a session field -

Is there any way, I can get some parameters from the header, cookies (log in userId in my case) , And then apply it in a form which I know who will deposit the ticket?

What is the call to apply the request, when I can use it (and also a good practice?) Edit An issue, absolutely deceiving anyone if I were to create a hidden area with this value. It could Ript, but the issue may be re-used in any way to verify and return the form, it can not be sure how it ....
