Pythonista for Python 3.x.
Are there any plans to release a Python 3.x variant of Pythonista?
@omz ah, I see. I had no idea (I've never done any iOS development).
Well, if you ever decide to release a separate version of pythonista for python 3, I'd buy it in a hearthbeat.
@omz What are your thoughts on registering on http://www.gittip.com ? This is not the first that folks have offered to fund specific areas of development. What do you view as the pros and cons of this approach to folks voting for things that are important to them?
@pdxmisfit That's a possibility I'm thinking about. My primary concern is that it would result in two versions of Pythonista that would be incompatible with each other, which could be very confusing for new users ("which one should I get?"), and potentially annoying when sharing iOS-specific scripts that might be only compatible with one or the other version. To someone not familiar with the compatibility issues of Python 2 vs 3, it could also look like a cash-grab to have two nearly-identical versions of the same app.
There are technical issues too of course (e.g. some of the bundled third-party modules aren't compatible with Python 3), but this is really the main problem that I see. Your offer is very generous, and I appreciate the gesture, but funding isn't really a factor here.
@ccc I think platforms like gittip or flattr are more appropriate for open source projects. Voting on features (especially with your wallet) always carries the risk of missing expectations (because software development is often unpredictable), and as I said, I don't really need the funding.
Python 2.7.6 release candidate 1 and Python 3.3.3 release candidate 1 were posted last Sunday to fix a pile of bugs but principally to solve the tkinter issues on the Mac which become more evident because <b>Mac OS X Mavericks installs Python 2.7.5</b> by default on all Macs.
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 <b>less than two years of Python 2 bug fixes</b>.
Even the Python 2 or Python 3 page has changed in favor of encouraging people to move now to Python 3.
Given all the progress that the community has made towards Python 3, it would be good to see Pythonista move forward to Python 3 as well.
print(sys.version_info) # 2.7.0 in Pythonista v1.3
UPDATE: Pythonista v1.4 now brings the Python version up to Python v2.7.5 which is the same version of Python installed by default on machines running Mac OS X Mavericks.
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.
