title: Counting number of lines in a JSON file using Python
body: <p>I have a .json file which contains a JSON item on every line. I want to try and count how many JSON items I have within the file using Python. I am currently just counting the lines using the following code</p>
  
  <pre><code>count =0
  with open(file) as f:
      for line in f:
          count+=1
  </code></pre>
  
  <p>This seems like an unefficient way of doing it though. Is there a more efficient way of either calculating the number of JSON items in a .json file or counting the number of lines within a file?</p>
