title: Convert a tuple to a list in a dictionary
body: <p>I have a GeoJSON output in the form of:</p>
  
  <pre><code>{'type': 'Point', 'coordinates': (0.00027777777777777827, 22.000138888888873)}
  </code></pre>
  
  <p>How can I convert the value of 'coordinates' from a tuple to a list while keeping 'type' as is?</p>
  
  <p>I've tried using <code>{k: [list(ti) for ti in v] for k, v in geom.items()}</code> as given <a href="https://stackoverflow.com/questions/47731301/convert-tuple-to-list-in-a-dictionary">here</a> where <code>geom = geometry.mapping(geometry.Point(x, y))</code>but it doesn't help.</p>
  
  <p>I see an error that says 'Float object is not iterable'</p>
  
  <p>I'm using the shapely library</p>
