How to get the second level key's of JSON using python?

Question

Below is content of JSON file, how can I get only the keys of the second level, that means I should be able to store the keys like uid,passid,signbuttonid,logoIcon,cornerSettingMenu,logoutButtonId,overlayId,loaderInFunctionalPanel this keys I should be able to store in a list or some array using python. means I need like

list[0]=  uid

list[1]=passid

list[2]=  signbuttonid

list[3]=logoIcon and so on . . . . . . 

{ "GlobalElements" : [ { "uid":"userEmail", "passid":"userPwd", "signbuttonid": "//button[@class='btn btn-mammoth']", "logoIcon":"//a[@class='logo text-hide']", "cornerSettingMenu":"//div[@class='dropdown-toggle']/p", "logoutButtonId":"//a[@class='logout']", "overlayId":"//div[@class='overlay']", "loaderInFunctionalPanel":"//div[@class='small-inline-loader']/child::i[@class='fa fa-spinner fa-pulse']" } ]

Note: I don't need values of that. I need only keys.

Can Anybody help me on this. Thanks in advance.

Solution 1

if

import json

a={ "GlobalElements" :[ { "uid":"userEmail", "passid":"userPwd", "signbuttonid": "//button[@class='btn btn-mammoth']", "logoIcon":"//a[@class='logo text-hide']", "cornerSettingMenu":"//div[@class='dropdown-toggle']/p", "logoutButtonId":"//a[@class='logout']", "overlayId":"//div[@class='overlay']", "loaderInFunctionalPanel":"//div[@class='small-inline-loader']/child::i[@class='fa fa-spinner fa-pulse']" } ]}

a= json.dumps(a) #serialize dictionary to json

b=json.loads(a)  #unserialize json to get dictionary

get the list of keys with :

l= b["GlobalElements"][0].keys()
print l

[u'uid', u'logoutButtonId', u'logoIcon', u'signbuttonid', u'passid', u'overlayId', u'loaderInFunctionalPanel', u'cornerSettingMenu']

Solution 2

a={ "GlobalElements" :[ { "uid":"userEmail", "passid":"userPwd", "signbuttonid": "//button[@class='btn btn-mammoth']", "logoIcon":"//a[@class='logo text-hide']", "cornerSettingMenu":"//div[@class='dropdown-toggle']/p", "logoutButtonId":"//a[@class='logout']", "overlayId":"//div[@class='overlay']", "loaderInFunctionalPanel":"//div[@class='small-inline-loader']/child::i[@class='fa fa-spinner fa-pulse']" } ]}

l= a["GlobalElements"][0].keys()
print l[0]
print l[1]
print l[2] so on or using for loop worked for me.

Thank you.

First you need to import json store your json content in a variable. if it is in a file, read the file and store it in variable. Use dumps() and loads() method to serialize and unserialize and just take the values as below code

import json

x={ "GlobalElements" :[ { "uid":"userEmail", "passid":"userPwd", "signbuttonid": "//button[@class='some id']", "logoIcon":"//a[@class='some id']", "cornerSettingMenu":"//div[@class='dropdown-toggle']/p", "logoutButtonId":"//a[@class='logout']", "overlayId":"//div[@class='overlay']", "loaderInFunctionalPanel":"//div[@class='small-inline-loader']/child::i[@class='fa fa-spinner fa-pulse']" }  ] }

x= json.dumps(x)

y=json.loads(y)
z= b["GlobalElements"][0].keys()

here z will be holding the first value of the second level.

Just get the keys from the second level dictionary with .keys() python dictionary docs

But it is giving whole uid,passid, singbuttonid so on, what I have to do if I need get only uid??

[Bart]

It gives you a list with the keys, like you wanted in your question

Yes, this Helped me and using index like l[0],l[1] helped me, Thank you.
