title: How to convert standard timedelta string to timedelta object
body: <p>What is the simplest way to convert standard timedelta string to timedelta object?</p>
  
  <p>I have printed several timedelta objects and got these strings:</p>
  
  <pre><code>'1157 days, 9:46:39'
  '12:00:01.824952'
  '-1 day, 23:59:31.859767'
  </code></pre>
  
  <p>I know I could write parser myself, but is there any simpler solution?</p>
