Changes to the original context will not be reflected in the geometry object. Parameters ---------- context : a GeoJSON-like dict, which provides a "type" member describing the type of the geometry and "coordinates" member providing a list of coordinates, or an object which implements __geo_interface__. Returns ------- Geometry object Examples -------- Create a Point from GeoJSON, and then create a copy using __geo_interface__. >>> from shapely.geometry import shape >>> context = {'type': 'Point', 'coordinates': [0, 1]} >>> geom = shape(context) >>> geom.geom_type == 'Point' True >>> geom.wkt 'POINT (0 1)' >>> geom2 = shape(geom) >>> geom == geom2 True __geo_interface__typefeaturegeometryrrr linearringrrNrrrcSs g|] }|d|ddgqS)rr-Nr).0crrr qs zshape..geometrycollectioncSsg|]}t|qSr)shape)r.grrrr0ss geometriesr)hasattrr(getlowerrrrrr r rrrrr)contextobrgeomsrrrr26s6 !     r2cCs|jS)aReturn a GeoJSON-like mapping.
