Python3

[kseistrup]

Please support Python3.

I'd likely say that someone will eventually port it.

The developer probably wanted to reach as many people as possible as easy as possible. Most OS's such as Mac and popular Linux builds all have Python 2.7 by default.

[kseistrup]

(For certain values of “popular”, yes. ArchLinux has Python3 as its default.)

I agree, I just wanted to make sure there was a formal issue concerning this.

[HelloZeroNet]

Yes the main reason was the fact that most linux distribution comes with Python 2 and it has more mature libraries. (and the speed is also somewhat better)

Some months ago the gevent event library ported to Python 3, so I think it shouldn't be hard to make the project compatible both with Python 2 and 3.

I've started work on this, hopefully we can get a couple PRs going until we have full agnostic support.

@DoWhileGeek cool! 👍

Python 2 is now less than three years from the chopping block. 🔪

ZeroNet's transition to Python 3 needs to be feature complete before 2020, Python 2.7's proposed end-of-life (EOL) date. While feasible and indeed necessary, this transition is likely to prove non-trivial – which is to say, "It's gonna hurt." There's really no getting around that. six helps, but it's no panacea. The syntactic and semantic differences between Python 2 and 3 are sufficiently profound (particularly with respect to string handling) that the two could be said to be different languages entirely – albeit closely related languages.

Ssomeone just needs to bite the thankless bullet and start doing it. The sooner this painful migration begins, the sooner this painful migration ends. Or to paraphrase an ancient Chinese and/or African proverb:

The best time to migrate to Python 3 was two years ago. The second best time is today.

I wonder how do other python projects cope with this problem. How do they manage to run on both 2.X and 3.X systems? Do they all have to use some compatibility interfaces with two implementations behind them?

[skwerlman]

there are compatibility mechanisms in python to help handle the transition, like the six library, and from __future__ import foo

@HelloZeroNet Please, add some labels on this issue, it's important.
