給定一些坐標，我試圖繪制多邊形的外部邊界。但是使用我在下面附上的代碼：from shapely.geometry import Polygonlat_point_list = [42.108288,42.13397,42.087456,42.085308000000005,42.087456,42.13397,42.095806,                  42.085308000000005,42.10305,42.108288,42.10305,42.095806]lon_point_list = [14.272663, 14.218105, 14.185248999999999,14.213285999999998,14.185248999999999,                  14.218105, 14.261092999999999, 14.213285999999998, 14.268307, 14.272663, 14.268307, 14.261092999999999]                            polygon_geom = Polygon(zip(lon_point_list, lat_point_list))polygon_geom我得到：我怎樣才能只得到外部邊界，而沒有邊界內的交叉線？
