How to print the complete json array using python?
Question: I have a json array. And need to print only the id using python .How do i do
it ?

This is my json array :

    
    
    {
    "messages":
      [
       {
    
       "id": "1531cf7d9e03e527",
       "threadId": "1531cf7d9e03e527"
       },
    
       {
       "id": "1531cdafbcb4a0e6",
       "threadId": "1531bfccfceb1ed7"
       }
    
     ],
    
     "nextPageToken": "01647645424797380808",
    
     "resultSizeEstimate": 103
    }
    

*EDIT : *

I am actually writing a python code to get messages from the gmail API. This
program gives the message ids and thread ids of a gmail accounts' messages as
a json format. I only need the message id and not the thread id.

Answer: 
    import json
    dict_result = json.loads(your_json)
    ids = [message['id'] for message in dict_result['messages']]
