python reverse/transponse a dictionary -


इस सवाल का पहले से ही एक उत्तर है: < / p>

  • 3 जवाब

    मैं एक tranpose करने के लिए देख रहा हूँ अजगर पर शब्दकोश और चारों ओर देखकर मैं इसके लिए एक समाधान ifnd करने में सक्षम नहीं था। क्या किसी को पता है कि मैं निम्नलिखित जैसे इनपुट के रूप में एक शब्दकोश को बदल सकता हूं: 

      ग्राफ = {'ए': ['बी', 'सी'], 'बी': [ '' 'डी': ['डी'], 'डी': ['सी'], 'ई': ['एफ'], 'एफ': ['सी']} < / code>   
     ताकि मुझे कुछ मिलता है:  
      newgraph = {'A': [']],' बी ': [' ए '', 'सी': ['ए', 'बी', 'डी', 'एफ'], 'डी': ['बी', 'सी'], 'ई': [''], 'एफ ': [' ई ']}    
     
     
     उपयोग करें:  
      newgraph = defaultdict (सूची) के लिए, graph.items () में adj: adj: newgraph [y] के लिए .append (x)   
     हालांकि यह नहीं है खाली सूची में रिक्त स्ट्रिंग  ''  रखने का कोई मतलब नहीं है, यह निश्चित रूप से संभव है:   xg के लिए  new code: newgraph [x] = newgraph [ x] या [']]

c# - Use custom conventions when persisting Rebus sagas in MongoDb -

When I store my domain in mangodibi, I use a custom convention (as stated) I have been here to continue my songs as they represent the string, since we found it easy during debugging. I want to do this in the form of storage as my saga using Reebus using Mogodibi. Is there any way to do this? Okay, my bad ... conventions are used globally in the Conventions Registry var conference = new meeting pack (); Conferences Add (New EnumSerializationConvention (BsonType.String)); ConventionRegistry.Register ("Saga Conventions", Conventions, x => True); The key is the third parameter of the register method, which acts as a filter for selection of which class has been affected by the conference (in my case I was filtered by namespace , And that is because the sonnet data was not correct).
