ENH: Fixed python errors

 ### Description
-==Description==
+k==Description==
 This is a demonstration of how to construct and display geometric objects using the classes derived from vtkCell3D. For each object we specify the points and cell Ids. 
 
-From this we create an unstructured grid. In some cases a vtkCellArray is used and the result is added to the unstructured grid, see: '''''MakePolyhedron()''''' and '''''MakeTetrahedron()'''''.
+From this we create an unstructured grid. In some cases a vtkCellArray is used and the result is added to the unstructured grid, see: MakePolyhedron() and MakeTetrahedron().
 
 Also demonstrated is the use of vectors to hold the unstructured grids, mappers, actors and renderers.
