title: Create a List from a string in Python
body: <p>I am new to pyhon and i can't find a way to manipulate a string of mine into a List.</p>
  <p>I read a file that contain this exact output (it is one parameter of a csv file):</p>
  <pre><code>[{a,b,c},{aa,bb,cc}]
  </code></pre>
  <p>I want to format that string to get an array of 2 objects :</p>
  <pre><code>[{
      val_a: 'a',
      val_b: 'b',
      val_c: 'c'
  },
  {
      val_a: 'aa',
      val_b: 'bb',
      val_c: 'cc'
  }]
  </code></pre>
  <p>Is there a simple way of doing this ?</p>
