如何将wkt格式的多边形列表转换为多多边形？

from shapely.wkt import loads
from shapely.geometry import Polygon

# 示例WKT格式的多边形列表
wkt_polygons = [
    'POLYGON ((0 0, 0 1, 1 1, 1 0, 0 0))',
    'POLYGON ((1 1, 1 2, 2 2, 2 1, 1 1))'
]

# 解析WKT格式的多边形列表
polygons = [loads(wkt) for wkt in wkt_polygons]

# 转换为多多边形
multi_polygon = Polygon()
for polygon in polygons:
    multi_polygon = multi_polygon.union(polygon)

# 输出转换后的多多边形
print(multi_polygon.wkt)
