title: Geting error: 'Int64Index' object has no attribute 'get_values'. What am I doing wrong?
body: <p>I'm kinda new to Data Science and I'm struggling with this project, I would appreciate some help. So, I'm working with some .shp files to get some choropleth-like maps with some other functions, that for my luck are not working because of this error I'm getting.</p>
  <pre><code>shp_path = '.../Comuna.shp'
  sf = shp.Reader(shp_path)
  
     def read_shapefile(sf):
       fields = [x[0] for x in sf.fields][1:]
       records = sf.records()
       shps = [s.points for s in sf.shapes()]
  
  df = pd.DataFrame(columns=fields, data=records)
  df = df.assign(coords=shps)
  
  return df
  
  df = read_shapefile(sf)

  <p>I've built some other functions to get this maps, but I think the root of the problem is this one.
  Thanks a lot.</p>
