These are all 2to3 errors, so not technically errors?

@darribas, maybe run 2to3 on these notebooks as part of the buildscript, or we just fix these once & move on.

[darribas]

yeah I could add that script run on the build process. Do you have any pointers on where to find it/how to run it?

More generally, shouldn't notebooks be Python-3 first in all projects in the federation by now? If so, I'm happy to issue a fix upstream on the notebooks.
