我正在嘗試從 JSON 數(shù)據(jù)集中從馬薩諸塞州波士頓的多個(gè)社區(qū)中提取坐標(biāo)，但我一直在嘗試獲取每個(gè)城市的第一個(gè)坐標(biāo)對(duì)；下面是 Roslindale 坐標(biāo)的縮小版。"features": [{ "type": "Feature", "properties": { "Name": "Roslindale", "Acres": 1605.5682375, "SqMiles": 2.51, }, "geometry": { "type": "MultiPolygon", "coordinates": [ [ [ [ -71.125927174853857, 42.272013107957406 ], [ -71.125927174853857, 42.272013107957406 ] ] ], [ [ [ -71.125830766767592, 42.272212845889705 ], [ -71.125830766767592, 42.272212845889705 ] ] ], [ [ [ -71.125767203228904, 42.272315958536389 ], [ -71.125767203228904, 42.272315958536389 ] ] ] ] } },現(xiàn)在我已經(jīng)提取了我想要使用的數(shù)據(jù)for data in boston_neighborhoods: neighborhood_name = data['properties']['Name'] neighborhood_id = data['properties']['Neighborhood_ID'] neighborhood_size = data['properties']['SqMiles'] neighborhood_latlon = data['geometry']['coordinates'] neighborhood_lat = neighborhood_latlon neighborhood_lon = neighborhood_latlon neighborhoods = neighborhoods.append({'Neighborhood': neighborhood_name, 'Neighborhood_ID': neighborhood_id, 'SqMiles': neighborhood_size, 'Latitude': neighborhood_lat, 'Longitude': neighborhood_lon}, ignore_index=True)這將返回多個(gè)坐標(biāo)對(duì)，但我只想要第一對(duì)，下面是我現(xiàn)在返回的示例輸出：Latitude | Longitude --------------------------------------------------------[[[[-71.12592717485386, | [[[[-71.12592717485386, 42.272013107957406], [... | 42.272013107957406], [...
