shapely.is_prepared

is_prepared(geometry, **kwargs)

Returns True if a Geometry is prepared.

Note that it is not necessary to check if a geometry is already prepared before preparing it. It is more efficient to call prepare directly because it will skip geometries that are already prepared.

This function will return False for missing geometries (None).

Parameters:

geometryGeometry or array_like

**kwargs

For other keyword-only arguments, see the NumPy ufunc docs.
