User Story: Work seamlessly for years to come

[renemarc]

User Story

As a developer, I want the image to run on Python 3 so that I can have this project still working for the foreseeable future.

Acceptance Criteria

1. It's done when the code and its dependencies work on Python 3.
2. It's done when base images are now using Python 3.

Additional Details (if any)

• Python 2.7 EOL is January 1st 2020: https://www.python.org/dev/peps/pep-0373/

While I was adding support for the Wave Plus to my fork I also successfully upgraded it to Python 3 (using balenalib/raspberrypi3-alpine-python:3 as the base image).

If you're interested, I would gladly cook up a pull request containing the necessary changes.
