title: how to replace values of dictionary with another dictionary values
body: <p>Hi I have two lists which contain some dictionary with their values</p>
  <pre><code>list1 = [{'val-1': 0, 'val-2': 0, 'val-3': 0}, {'val-1': 0, 'val-2': 0, 'val-3': 0}, {'val-4': 0, 
  'val-5': 0, 'val-6': 0}]
  
  list2 = [{'val-1': 90, 'val-4': 89, 'val-3': 99}, {'val-2': 88, 'val-6': 55, 'val-1':100}]
  </code></pre>
  <p>The desired output would be something like this</p>
  <pre><code>output: [{'val-1': 90, 'val-2': 88, 'val-3': 99}, {'val-1': 90, 'val-2': 88, 'val-3': 99}, {'val-4': 
  89,'val-5': 0, 'val-6': 55}]
  </code></pre>
  <p>How could I make this replacement?</p>
  <p>what I did form list2 I select each dictionary and compare and replace the values present in list1 all dictionary</p>
  <p>but I didn't get the correct output</p>
