title: Merge few lists into dictionary
body: <p>I have 3 lists:</p>
  
  <pre><code>a = ["John", "Archie", "Levi"]
  b = ["13", "20"]
  c = ["m", "m", "m", "m"]
  </code></pre>
  
  <p>I want to merge this into one list with dictionaries:</p>
  
  <pre><code>    result = [
  {"name": "John", "age": "13", "gender": "m"},
  {"name": "Archie", "age": "20", "gender": "m"},
  {"name": "Levi", "age": "", "gender": "m"},
  {"name": "", "age": "", "gender": "m"},
      ]
  </code></pre>
