python - 多次更新 shapefile 中的数据

Question

我尝试在现有的 shapefile 中进行扩展（如果没有，我创建它然后扩展它）。我在扩展和附加方面遇到了问题，比如知道我是否应该做“data.append(list(pointlist))”，我总是得到一个

AttributeError：“多边形”对象没有属性“几何”

if os.path.isfile([name ".shp"])==False:
 save_shp(name,poly)
else:
 open_shp(name,poly)

if os.path.isfile([name ".shp"])==False:
 save_shp(name,pointlist,area)
else:
 open_shp(name,pointlist,area)

#def open_shp(name,data1,data2=None):

#        data=nc['geometry'].append(data1)
#        shp = gpd.GeoDataFrame(geometry=data)
#        shp.set_crs(epsg=4326, inplace=True)  
#        shp.to_file([name +".shp"])
