  <p>I have a string value which has value like this:</p>
  
  <pre><code>"[(1,2,3),(2,3),(6,8)]" -&gt; string
  </code></pre>
  
  <p>but I want to have these values in int type like this:</p>
  
  <pre><code>[(1,2,3),(2,3),(6,8)] -&gt;   (int list) list
  </code></pre>
  
  <p>what should I do?is there any function which can help me? or I have to do it myself?</p>
