Pythonista for Python 3.x.
ungaa last edited by
Pythonista should eventually move over to Python 3. It has improved syntax, new features, and is the current standard. Python 2.7 will be phased out eventually. The only technical reason you mentioned, that lack of PIL on Python 3, is not much of a reason at all. PIL is essentially obsolete now. The Python community is largely moving to better maintained backwards compatible forks of PIL, such as Pillow, which has more features, fewer bugs, and is fully compatible with Python 3.
With that said, there is no urgency in moving Pythonista over to Python 3. I would welcome two separate versions of Pythonista for Python 2 and Python 3, but it isn't really necessary yet.
What I would really appreciate soon is a new version of Pythonista that includes Python 2.7.5 and is compatible with iOS 7. There are many bugs that significantly impair the usability of Pythonista on iOS 7, and roughly 3/4 of all iOS users are running iOS 7 now. If funding is an issue (though it doesn't seem to be), I and likely many other Pythonista users would be willing to help out.

Hi, I've purchased Pythonista today. I got to say it's the best Python IDE I've ever seen on iOS. However I'm very disappointed to see that it doesn't support Python 3. Is there something we as a community can do to help you update the current Pythonista app to Python 3?
I'm also willing to invest in any way that I can if the current app gets updated and not a new app released just for Python 3. As I do have a strong requirement for Python 3.
Python 3 is the future, Python 2 is phasing out there's no doubt about it.

Would second that as well. I've only just learned Python 3 and doesn't know anything about the previous Pythons. I bought Pythonista because everyone says it's best on the platform only to find I can't really use it. LOL

I am also a newbie, learning Python for a Bioinformatics Algorithms course. They reccommened Python 3, so that's what I started with. I'd be happy to pay again for a Pythonista 3 version, too. The cost is not a big issue if it works.

I'm also greedy for a python 3 version :-)
It's clear that python 3 is the future (and present) and python 2.7 is the past (and present).
At sometime the transition time will be almost over and everybody will use python 3, except for some legacy stuff.
Archlinux has python3 as default, fedora and ubuntu will follow next year.
Because we are in a transition time, a newbie needs to deal with this topic at the moment.
As long as he doesn't needs a library wich only is supported in python 2.7 it would be a bad idea to start a new project in python 2.7.
So I hope that after the big ios 7 update, python 3 is next for pythonista :-)
I don't mind to have two pythonista version in the appstore. A python newbie needs to be confronted with this version stuff, at the moment.
Or your could make an in-app purchase for python 3, and later on at some time you can switch to python 3 as the default a make python 2 an in app purchase.
In pythonista you could have to separate workspaces and environments one for python 2 and one for python 3.
Python 3 is now five years old!! https://mail.python.org/pipermail/python-dev/2013-December/130673.html

+1 for python 3.
please make it happen.
i also like the idea of an in app purchase.
I would be happy to pay all over again to get Python 3.
My guess would be that a single app that supports both Python 2 and 3 would be too big and confusing both for the developer and the user.
Remember that Python has all those "batteries included" standard library modules as well as extensive documentation so it would be a big executable. The current Pythonista is already a 40MB download from the App Store. Size matters but there is also the confusion factor...
The standard libraries are often the same but sometimes subtly different between Python 2 and Python 3. How does the user specify whether a particular script should be run as P2 or P3? What about text typed into the command line interpreter? Context sensitive help has a similar problem: Does help display the routine from the P2 docs or the P3 docs? Also, for the developer it is confusing to build and test all bugs in both P2 and in P3 in the same build. As bug reports come in, are the for P2 or P3, etc.
If OMZ were to dare to take on Python 3 then I would gladly purchase the new product from the App Store because it would be a very serious investment of his time and focus to deliver a great Python 3 to iOS developers.
For a cautionary tale about divided focus, see another Python app for iOS that put out 8 different versions of their Python app before abandoning its community at the beginning of this year. It is better to have a single great Pythonista that is updated and supported than divide focus too early.

New year! New hope for a python 3 version of pythonista :-)
@omz some new thoughts about this topic?
Given that Python PEP 373 projects that Python 2.7.9 will be released in May 2015 and that Python PEP 404 makes clear that there will never be a Python v2.8, there are just one more year of Python 2 bug fixes. NOTE: This EOL deadline was later extended 5 additional years to 2020 as discussed later in this thread.
Given all the progress that the community has made on Python 3, it would be good to see Pythonista move forward to Python 3 as well.

I believe all the included third-party modules should now support Python 3, so they should no longer be a hold up.

With Python 3.4 now out and 2.7 approaching EOL (final maintenance release planned next year), I think it's a good time to start moving on to Python 3. Python 3 first came out in 2008 and is now the the default language for most new projects. All important libraries that one would want on Pythonista are available on Python 3, or have superior replacements available on Python 3. Switching to Python 3 will make it easier for those that are running Python 3 on the desktop.
The switch is inevitable and Python 3 has been out for 5.5 years now. It's time to move forward,

There's always 'Python 3.3 for iOS' which is $3 or 'Pythoni3.3' which is free.

Gonna put my word in. I don't really need Python 3, but it may be pretty nice to have Pythonista support Py3. Maybe you can make it so users can switch, which language they want to use (in one program), thought it might be pretty hard. Or (I think a better way) you can release another Pythonista for Py3. And yea, as ungaa said, Py3 was out for a Pretty Long Time...

I agree with ShadowSlayer that two separate apps woulde be most practical.
I am very well willing to pay for a Python 3.4 version.
When can we expect a new version (2.7 or 3.0)?
Python 2 End Of Life extended until 2020!! http://hg.python.org/peps/rev/76d43e52d978
Personally, I believe this is not a good idea because it will further slow Python 3 adoption. However, I do understand the pressure to go even slower than molasses.

Honestly my preference would be for a single app containing both 2.7 and 3.4, with a preference setting for which interpreter and lib directory gets used at startup. Yes, I'd have to pay for the extra 30+MB of iOS storage to hold that redundancy, but it means there's just one app, and it becomes possible (with an app restart potentially) to switch back and forth as needed.
Also I would happily pay $20 for Pythonista.

For those of us on slow "broadband" lines a double-sized binary would not be that welcome. I would think a separate app, with the old one disappearing over time and stabilised somewhere in between, would be best.

As I said before, this is technically not possible on iOS. The size of the app is not a factor here, but it has to be a single binary (statically linked) which wouldn't work with two different versions of Python.
To be more precise, it would technically be possible, but it requires dynamic linking, which is definitely not allowed by Apple. There is absolutely no chance this would get through review.

I haven't read the whole of this thread so I'm not sure if it's been raised already but is there any reason why you can't have a single 2.7 distribution and a 3.4 version that's only available via an IAP. It's a separate app but not one that's publicly available on the App Store. I recently looked into Python training courses at a number of UK colleges for a client of mine and they're still teaching 2.7 in the main but making students available ref the changes/differences/benefits of 3.4.
I'd expect that a good number of Ole's customers pick up Pythonista as a learning tool because is the superb built in documentation. With this being the case it's probably best if the main distribution mirrors what people are being taught in college. I'm not averse to two separate versions being available but it could prove very confusing for Python beginners so I fully understand and appreciate Ole's stance on this so far.
