[py2py3] Migration at level scr/python/A/B/C - slice 2

[mapellidario]

Intro

Our purpose is to continue with the gradual migration. This is the second slice in which the migration has been divided into. We have split migration units at level src/python/A/B/C.

A detailed plan of the migration at this depth is available at the dmwm mkdocs detailed plan page, with summary information on top.

Impact of the new feature

We start migrating the second bulk of migration units at src/python/A/B/C level, which will include:

Run futurize on the first bulk of units and then apply the necessary manual changes.
