Port to Python 3

[quozl]

Port the activity to Python 3 and the Sugar Toolkit for GTK+ 3.

Requires some of sugarlabs/sugar-toolkit-gtk3#382 to be completed.

@quozl any need to keep this issue open?

Thanks for asking. Happy to explain. Best reason is that #3 is not yet merged.

Why is it not yet merged? There's more to our ecosystem than GitHub. While we have released v0.113 of the toolkit, with Python 3 support, it has not been packaged by Ubuntu or Fedora yet, so there's no rush to merge Python 3 ports of activities since there is no place that they can be used, and if they are released accidentally the systems running v0.112 of the toolkit will fail to run them. This quandry is possibly called a "flag day change". I'm trying to control for that, see sugarlabs/sugar-docs@af47a5a for a recent example.

On the other hand, Hello World is not a core activity; it actually does nothing but serve as an example.

This isn't really the right place to discuss this, because so few people are watching this repository, but here's my current plan; either;

• keep the pull requests open until both Fedora and Ubuntu have packaged v0.113 for Python 2 and Python 3,
• merge the pull requests into a python3 branch, or;
• create a python2 branch for ongoing maintenance and merge the pull requests into master branch.

A better place to discuss would be the sugar-devel@ mailing list.

@quozl . I agree with you, we can merge into master after v0.113 gets packaged by Ubuntu or Fedora. It would be better to merge it into python3 branch now. Just going through the work done till now in the port to python 3 project for GSoC '19 proposal. Thanks for answering 😅 .

It is in python3 branch now, thanks.
