A Look Back At Python 3.0 After 10 Years

[TheBlackCat]

The Deluge BitTorrent client is pretty popular and has not been ported to python 3.

Whether applications support python 3 is less of an issue, it is mostly hidden from users. The question is whether python libraries (i.e. packages) are ported. It is hard to find a major one now that isn't either ported or in the process of being ported. There are really only three major projects that haven't had a compatible release yet, and two of those are ported in master while the last is basically only used internally by mozilla and is in the process of being ported. Further, several major ones have dropped Python 2 support, and many others will do so within the next two years.

The reason aiohttp isn't part of standard library, is the same reason that requests isn't part of standard library.
They don't want to be pinned down, as they are improving/changing at a much faster rate than python itself.

Also, there is a reliable packaging system that makes it super easy to include extra dependencies in your project.

And still so many things haven't been ported yet from Python 2 to 3...

We're now well over the peak and Python 2 is sliding down the hill at an increasing rate. I've not come across any packages I wanted that aren't Python 3 compat for a long, long time, but the opposite is increasingly true.

That reminds me. I have to evaluate whether it's feasible to port certain intentionally-GTK2 programs of mine from PyGTK to PyGI so I can use Python 3 for them or whether GTK+ 2.x's support for GObject Introspection is simply too immature.

To my knowledge, there is almost nothing worth caring about that hasn't been ported. If a program or library is still on Python 2, it is likely outdated or niche.

Isn't there also Twisted framework for asynchronous HTTP? I like twisted due to how you can use it on many different event notification systems and how many modules can share the same event loop. Of course you have to install it, which shouldn't be that hard to do.

I think you're right, though I personally haven't used Twisted much. It was way too overkill for my needs, and as a result, needlessly overcomplicated. But, it does seem to serve a lot of purposes that other libraries don't seem to do.
My main interest with Python+HTTP is WebSocket. Twisted supports that too, but not in an elegant way. It's been a while since I've checked, but there was this very basic library that accomplished WebSocket with far less effort and was only a couple hundred KB.

What's wrong with using aiohttp? Also depending on what you're trying to do, you can always try the multiprocessing or thread libraries. Note the latter keeps your application single-threaded, but from what I recall, it makes memory management easier.

One of my gripes with Python 3 is that the built-in HTTP client is not asynchronous.
To perform asynchronous HTTP requests you have to rely on a third-party library such as aiohttp.
