Check if a polygon is a multipolygon in Shapely
Use the object.geom_type string (see general attributes and methods).
For example:
if poly.geom_type == 'MultiPolygon': # do multipolygon things.elif poly.geom_type == 'Polygon': # do polygon things.else: # raise IOError('Shape is not a polygon.')
Ok, this worked for me:
print ('type = ', type(poly))outputs with:
type = <class 'shapely.geometry.polygon.Polygon'>in case of a polygon, and:
type = <class 'shapely.geometry.multipolygon.MultiPolygon'>in case of a multipolygon.
To check if a variable is a polygon or a multypolygon I did this:
if (isinstance(poly, shapely.geometry.multipolygon.MultiPolygon)): code...
