Question

我正在执行查询以通过python读取数据的几何形状。结果返回为元组。我需要将其转换为适合几何形状的形状。如何转换？

    def read_geom(self,data_date,date):
        cur = self.conn.cursor()
        query = 'select ST_AsText("geom") from "%s_liveability_%s" ORDER BY "il kodu"' %(data_date,date)
        cur.execute(query)
        result = cur.fetchall()
        return result
        cur.close()

geom=P.read_geom(data_date,date[0])

from shapely.geometry import mapping, Polygon
import fiona
from shapely import wkb


# Here's an example Shapely geometry
for parcel in geom:
    parcel.geom = wkb.loads(geom.Multipolygon, hex=True)

运行脚本

runfile('C:/Users/Bugra/Desktop/shpp.py', wdir='C:/Users/Bugra/Desktop')

runfile('C:/Users/Bugra/Desktop/shpp.py', wdir='C:/Users/Bugra/Desktop')

    'geometry': mapping(poly),

    return ob.__geo_interface__

AttributeError: 'tuple' object has no attribute '__geo_interface__'

如何将几何查询结果转换为合适的形状几何？
