Package: paraview Followup-For: Bug #959677 The calculator seems to be working fine e.g. tutorial steps at https://docs.paraview.org/en/latest/UsersGuide/filteringData.html#python-calculator change the colour of the sphere depending on the value entered in the calculator.
Can you confirm you installed python3-paraview? It is required for the paraview python functionality. I think this bug can be closed.
