title: Convert string dictionnary into dictionnary format
body: <p>I try to convert a string value into Dictionary format. I must respect this syntax but when I try to convert the string value into a dictionary I have a error. The json.load convert the bracket nested into a string and not into a dictionary format.</p>
  <p>Do you have any idea to resolve this ?</p>
  <pre><code>    import json
      dict_info = &quot;{\&quot;strategy\&quot; : \&quot;&quot; + &quot;ok&quot; + &quot;\&quot;, \&quot;aa\&quot; : \&quot;&quot; + &quot;{\&quot;strategy\&quot; : \&quot;&quot; + 
      &quot;strg&quot; + &quot;\&quot;}&quot; + &quot;\&quot;}&quot;
      json.loads(dict_info)
  </code></pre>
  <p>Thank you</p>
