title: How to write content back to a json file using python?
body: <p>I have a json file which looks like <a href="https://www.dropbox.com/s/raplkyl5le1rmh9/testDehil.json?dl=0" rel="nofollow">https://www.dropbox.com/s/raplkyl5le1rmh9/testDehil.json?dl=0</a> </p>
  
  <p>My task was to read the address and find the <strong>full specific geo-code</strong> and update back the json file. I am able to do the following till now:</p>
  
  <p>--> Read the jsonfile and pass the address to Google API to get the exact latitute and longitude.</p>
  
  <p>I am stuck at this point where i need to update the read file to the newly received exact latitude and longitude. </p>
  
  <p>My code is :</p>
  
  <pre><code>import json
  import requests
  import time
  import shutil
  import os
  from pprint import pprint
  
  def open_json():
    with open('/home/nishant/Documents/Python/Gnitin/testDehil.json') as json_data:
       d = json.load(json_data)
       #json_data.close()
       #pprint(d) 
       for item in d: 
         a = item['address']['address']
         google_call(a)
         time.sleep(10)
       # EXTRACT THE address from each and pass it below: ## 
  
  
  
  def google_call(add):
     address = add  #This needs to be run in loop
     api_key = "XXXXXXXXXXXXXXXXXXXXX"
     api_response = requests.get('https://maps.googleapis.com/maps/api/geocode/json?address={0}&amp;key={1}'.format(address, api_key))
     api_response_dict = api_response.json()
  
     if api_response_dict['status'] == 'OK':
        latitude = api_response_dict['results'][0]['geometry']['location']['lat']
        longitude = api_response_dict['results'][0]['geometry']['location']['lng']
        print 'Latitude:', latitude
        print 'Longitude:', longitude
        write_back_cool_stuff(latitude,longitude)
  
  def write_back_cool_stuff(lat,lon):
