For example:

```cpp
   vtkSmartPointer<vtkPolyData> poly = vtkSmartPointer<vtkPolyData>::New();
    poly->SetPoints( points );
    poly->SetLines( segments );
    poly->GetCellData()->SetScalars( dataIndexes );

```

Ports to:

```python
   poly = vtk.vtkPolyData()
   poly.SetPoints( points )
   poly.SetLines( segments )
   poly.GetCellData().SetScalars( dataIndexes )

```
