Bug#950539: SyntaxWarning: "is" with a literal. Did you mean "=="?

[Philipp Marek]

Package: python3-vtk7
Version: 7.1.1+dfsg2-1+b2
Severity: normal

Upon installation, I get this message:

     libpdal-plugin-faux (2.0.1+ds-1+b1) wird eingerichtet ...
     libopencv-videoio4.2:amd64 (4.2.0+dfsg-4) wird eingerichtet ...
     python3-vtk7 (7.1.1+dfsg2-1+b2) wird eingerichtet ...
     
/usr/lib/python3/dist-packages/vtk/numpy_interface/algorithms.py:200: 
SyntaxWarning: "is" with a literal. Did you mean "=="?
       if max_dims is 1:
     libpdal-plugin-sqlite (2.0.1+ds-1+b1) wird eingerichtet ...

I guess that's not expected.
