Thanks, there were some references to GNU Radio 3.6-style blocks. I've
updated the tutorial to reflect that.

Did you add a test for the Python block? (Perhaps there's a problem
in the Python, which would show up here).

Yes there is, but I'm not sure that's the problem. I couldn't replicate
your problem, however.
- your Python block works correctly (unit test it)
- the XML definition for the GRC block is correct
- everything is installed correctly.
Perhaps you want to go over the tutorial with the updated info again.
