title: Combining shapefiles in Python / GeoPandas
body: <p>I have three polygon shapefiles which overlap each other. Let's call them:</p>
  
  <ul>
  <li>file_one.shp (polygon Name is 1)</li>
  <li>file_two.shp (polygon Name is 2)</li>
  <li>file_three.shp (polygon Name is 3)</li>
  </ul>
  
  <p>I want to combine them and keep the values like this.</p>
