title: Loop json objects and add element together with value through user input
body: <p>If I have a json file with multiple json objects such as following</p>
  
  <pre><code>{"created_at":"Sun Apr 16 02:00:14 +0000 2017","id":853427785339084800,"id_str":"853427785339084800"}
  
  {"created_at":"Sun Apr 16 02:03:24 +0000 2017","id":853428582613475332,"id_str":"853428582613475332"}
  </code></pre>
  
  <p>I want to loop all the json objects add add new element together with value through user input in command line one by one. Is it possible because my format not in json array?</p>
  
  <pre><code>import json
  import pandas as pd
  from pprint import pprint
  
  tweets_data_path = 'data.json'
  
  tweets_data = []
  tweets_file = open(tweets_data_path, "r")
  for line in tweets_file:
      try:
          tweet = json.loads(line)
          tweets_data.append(tweet)
      except:
          continue
  
  pprint(tweets_data)
  </code></pre>
