Python _python The instance code of the data JSON format output

There is a requirement that the JSON format data be displayed in the standard output of Python, and if the indentation display looks good on the data, there are many things to do with the JSON package

Import JSON
 
date = {u ' versions ': [{u ' status ': U ' current ', U ' id ': U ' v2.3 ', U ' links ': [{u ' href ': U ' http://controller : 9292/v2/', U ' rel ': U ' Self '}]}, {u ' status ': U ' supported ', U ' id ': U ' v2.2 ', U ' links ': [{u ' href ': U ' http://controller:9292 /v2/', U ' rel ': U ' Self '}]}, {u ' status ': U ' supported ', U ' id ': U ' v2.1 ', U ' links ': [{u ' href ': U ' http://controller:9292/v2/' , U ' rel ': U ' Self '}]}, {u ' status ': U ' supported ', U ' id ': U ' v2.0 ', U ' links ': [{u ' href ': U ' http://controller:9292/v2/', U ' rel ': U ' Self '}]}, {u ' status ': U ' supported ', U ' id ': U ' v1.1 ', U ' links ': [{u ' href ': U ' http://controller:9292/v1/', U ' rel ': U ' Self '}]}, {u ' status ': U ' supported ', U ' id ': U ' v1.0 ', U ' links ': [{u ' href ': U ' http://controller:9292/v1/', U ' rel ': U ' self '}]}
 
print json.dumps (data, Sort_keys=true, indent=2) # sorted and indented two characters output

This will produce the following output:

{"
 versions": [
  {
   "id": "v2.3",
   "links": [
    {
     "href": "http://controller:9292/v2/",
     " Rel ":" Self "
    }
   ],
   " status ":" Current "
  },
  {
   " id ":" v2.2 ",
   " links ": [
    {
     ] href ":" http://controller:9292/v2/","
     rel ":" Self "
    }
   ],
   " status ":" Supported "
  },
  {
   "id": "v2.1", "
   links": [
    {
     "href": "http://controller:9292/v2/", "
     rel": "Self"
    }
   ],
   "status": "Supported"
  },
  {
   "id": "v2.0",
   "links": [
    {
     "href": "http:// controller:9292/v2/",
     " rel ":" Self "
    }
   ],
   " status ":" Supported "
  },
  {
   " id ":" V1.1 ",
   links": [
    {
     "href": "http://controller:9292/v1/",
     "rel": "Self"
    }
   ],
   " Status ': ' Supported '
  },
  {
   "id": "v1.0",
   "links": [
    {
     "href": "http://controller:9292 /v1/",
     " rel ":" Self "
    }
   ],
   " status ":" Supported "
  }
 ]
}

As you can see, it's all formatted.

This is in Python, if you use the command line directly, you want to convert directly, you can use data | Python-mjson.tool to output JSON-formatted data

Echo ' {' First_key ': ' Value ', ' second_key ': ' value2 '} ' | Python-mjson.tool

For example, to filter the value of First_key to the command line directly, you can:

Echo ' {' First_key ': ' Value ', ' second_key ': ' value2 '} ' | Python-c ' Import sys, JSON; Print Json.load (Sys.stdin) [sys.argv[1]] ' First_key

You'll get the value for that.

The above is a small series for everyone to bring the data JSON format of the output of the example code all content, I hope that we support cloud Habitat Community ~
