title: How to convert float to timedelta seconds in python?
body: <p>How do you instantiate a <code>datetime.timedelta</code> to a number of seconds in python? For example, 43880.6543</p>
  
  <p><strong>Edit (as per clarification by OP)</strong>: I have an Excel sheet, where a cell shows 43880.6543 (when the format is Generic) instead of a date. How do I convert this value to a <code>datetime</code> in python?</p>
