title: Python sort list of dictionary by float values
body: <p>The following is my list</p>
  <pre><code>List_data = [{'cases_covers': 0.1625}, {'headphone': 0.1988}, {'laptop': 0.2271}, {'mobile': 0.2501}, {'perfume': 0.4981}, {'shoe': 0.1896}, {'sunglass': 0.1693}]
  </code></pre>
  <p>Final answer should be like this:</p>
  <pre><code>[{'perfume': 0.4981}, {'mobile': 0.2501}, {'laptop': 0.2271}, {'headphone': 0.1988},{'shoe': 0.1896}, {'sunglass': 0.1693},{'cases_covers': 0.1625}]
  </code></pre>
  <p>i want them to be sorted based on the value of the key in descending order</p>
