Is there a way to list the names of the inputs in a Group Dataset filter with a programmable python filter?

I have a lot of point sources that I have grouped in paraview. Then I applied "Merge Blocks" and then the Programmable Python filter.

This is the code so far in the programmable filter:

Code:
pdi = self.GetInput()

npts = pdi.GetNumberOfPoints()
print npts

for i in range(0, npts):
        coord1 = pdi.GetPoint(i)
        print coord1
This code prints the coordinates of each point source. I would also like to print the names of the point sources, something like this:
PointSource1
PointSource5 etc.

I would appreciate your help.

It is possible to do it from the Python console in Paraview:

Code:
group_datasets = GetActiveSource()
for input_obj in group_datasets.Input:
    for (name, _), obj in GetSources().items():
        if obj == input_obj:
            print name
             break
However, this refers to the Paraview proxies, not the underlying VTK objects which you get in a programmable filter. If you just need to see which points come from different sources, you could use the programmable filter right after the Group Dataset filter and iterate over the vtkMultiBlockDataSet yourself and add a point array to each block containing index of the block. Perhaps not the best solution, but it could work
