[Paraview] Setting Source Object Attributes using a Python Script

[Olumide]

I've tried the ListProperties method. It has only two attributes:

 >>> src1.ListProperties()
['FileNames', 'TimestepValues']

 >>> for prop in src1:
...     print prop
...
Property name= FileNames value = ['D:/Data/Model.vtk']
Property name= TimestepValues value = []

Is there any other way to set the color and line thickness of a polyline?

Thanks,
