title: serializing JSON files with newlines in Python
body: <p>I am using json and jsonpickle sometimes to serialize objects to files, using the following function:</p>
  
  <pre><code>def json_serialize(obj, filename, use_jsonpickle=True):
      f = open(filename, 'w')
      if use_jsonpickle:
      import jsonpickle
      json_obj = jsonpickle.encode(obj)
      f.write(json_obj)
      else:
      simplejson.dump(obj, f) 
      f.close()
  </code></pre>
  
  <p>The problem is that if I serialize a dictionary for example, using "json_serialize(mydict, myfilename)" then the entire serialization gets put on one line.  This means that I can't grep the file for entries to be inspected by hand, like I would a CSV file. Is there a way to make it so each element of an object (e.g. each entry in a dict, or each element in a list) is placed on a separate line in the JSON output file?</p>
  
  <p>thanks.</p>
