In python you can use the following signatures of these methods:

int GetNextCell(vtkIdList *pts);
void GetCell(vtkIdType loc, vtkIdList* pts);

For example, in Python code,

idList = vtk.vtkIdList()

cellArray.GetNextCell(idList)
for i in range(cellArray.GetNumberOfIds()):
    id = cellArray.GetId(i)

You can see all the wrapped methods by using Python "help", like this:
help(vtk.vtkCellArray)
