It's not reasonable to expect a source code management system to display the last output of every Python script.
It might have been convenient for Jupyter notebooks, but that was a side effect of what's essentially a negative feature, the last output of every cell being thoroughly mixed with the source code.
You may see it as a negative feature, but i see it as a positive feature. I can push my notebooks to GitHub with the outputs and share them with others. Those people can see what the results are without having to setup and run the notebook.
This is incredibly useful for knowledge sharing and learning
Oh don't get me wrong, I have nothing against publishing notebooks, on GitHub or anywhere else. That was the convenient part. The negative feature was Jupyter mixing output into the file source code, making it difficult to version.
