title: How to insert a new key with a value in a specific position into a dictionary?
body: <p>I have a huge List of dictionary like this which has almost 100 entries. </p>
  
  <pre><code>[{ "color":-65536, 
    "touch_size":0.21960786,
    "touch_x":831.25,
    "touch_y":1597.2656
  },
  { "color":-65536,
    "touch_size":0.20392159,
    "touch_x":1302.5,
    "touch_y":1496.0938
  }, .... {}]
  </code></pre>
  
  <p>I want to insert 2 new keys with values in each dictionary on a particular position. </p>
  
  <pre><code>new_keys = ['touch_x_dp','touch_y_dp']
  </code></pre>
  
  <p><code>touch_x_dp</code> needs to be placed after key <code>touch_x</code> and <code>touch_y_dp</code> needs to be placed after <code>touch_y</code>
  The values for these need to be initialized with None. </p>
  
  <p>I have tried this but this does not place them where I need. </p>
  
  <pre><code>for key in dp_keys:data['attempts'][i]["items"][j][key]=None
  </code></pre>
