title: get list of selected objects as string Blender python
body: <p>I'm facing a rather easy to solve problem but I just don't know how to do it. I want blender to list all the objects selected as a string. Eg. if I run :</p>
  
  <pre><code>selection_names = bpy.context.selected_objects
  print (selection_names)
  </code></pre>
  
  <p>it gives me this line:</p>
  
  <pre><code>[bpy.data.objects['Cube.003'], bpy.data.objects['Cube.002'], bpy.data.objects['Cube.001'], bpy.data.objects['Cube']]
  </code></pre>
  
  <p>But what I want is for <code>selection_names</code> is to print out as:</p>
  
  <pre><code>['Cube.001','Cube.002','Cube.003','Cube']
  </code></pre>
