>>> from sedona.spark.geopandas import GeoSeries
>>> from shapely.geometry import Polygon
>>> s = GeoSeries(
...     [Polygon([(0, 0), (1, 1), (0, 1)]), None, Polygon([])]
... )
>>> s
0    POLYGON ((0 0, 1 1, 0 1, 0 0))
1                              None
2                     POLYGON EMPTY
dtype: geometry
```

```python theme={"system"}
>>> s.notna()
