Pythonista for Python 3.x.
-
Are there any plans to release a Python 3.x variant of Pythonista?
-
Not in the near future. There is <a href="http://pythonforios.com">Python 3.x for iOS</a> though (I'm not affiliated).
-
Sadly it is a poor second to Pythonista in terms of stability, usability, functionality, documentation, etc.
I gave up on it once I tried Pythonista ;-)
Noob to Python that I am. I assumed that 3.3 would be better to learn than 2.7. After asking around it appears that 2.7 is just what I need.
-
Edit: Fixed in Pythonista3 version 3.0 (300001) (currently in beta) which is Python 3.5.1.
I also echo the request to move on up to Python 3.3.1...
Also, how about Python 2.7.3 instead of the current 2.7.0.
import sys print(sys.version_info) # ==> sys.version_info(major=2, minor=7, micro=0, releaselevel='final', serial=0) print(sys.version) # ==> 2.7 (r27:82500, Feb 18 2013, 15:52:51) # ... [GCC 4.2.1 Compatible Apple LLVM 4.2 (clang-425.0.24)]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.

I agree about 2.7.3, I'm a little behind with that, though I don't think there are a lot of tangible benefits to get from that upgrade. Switching to Python 3.x is a lot more problematic because it's not backward-compatible. If I were to switch the current app to 3.x, a lot of scripts would simply not work anymore. There are also third-party libraries (like PIL, which Pythonista includes) that aren't yet compatible with Python 3.
-
I would also like a move to Python 3, because that is what we are moving to as our introductory teaching language and it would be fantastic to be able to recommend Pythonista to students. At the moment 2.7 is adequate. I don't know how <a href=http://python-imaging.github.com/Pillow/>Pillow</a> would fit in as a replacement for PIL.
-
At this point 2.7.3 should not be your target because Python 2.7.4 was due to be released 10 days ago: http://www.python.org/dev/peps/pep-0373/#release-schedule
-
I don't want to switch to Python 3 simply because I have been practicing Python 2.7 for a long while, but if necessary I will adjust..
-
I'm a bit confused, i thought the majority of people were still on 2.7, whats better about 3?
-
Python 3 is the better language, however many libraries and tools are still not compatible with it. Fortunately it seems to get traction now.
-
is there any reason to it being better, as in is it faster, more powerful has clearer syntax?
-
Improved / cleaned up syntax, better string handling (no string vs. unicode, and a separate bytes type for binary data), views and iterators instead of lists in many places, integer types cleaned up, standard library cleaned up... You get the idea.
All this clean up not only means that the language is easier to learn, it also makes future development of the language easier, as the developer don't have to bother with legacy stuff anymore.

06 April 2013 -- Python 2.7.4 & Python 3.2.4 & Python 3.3.1
From: http://www.python.org ...Saturday, April 6
Python 2.7.4
Python 3.2.4
Python 3.3.1Hi Ole,
Given that tomorrow is such a big day for Python releases, it triggers the following questions? Just out of curiosity, how much work is it for you to convert a new Python release into a new version of Pythonista? Is it a simple (automated) process or is it cumbrsome and time consuming? Do you just drop cPython into your bigger XCode project and then compile and go? Is there a lot of debugging to do each time? Do you need to apply patches to a bunch of modules to shoehorn them into the iOS?
Curious minds want to know... Best of luck on upgrading us to 2.7.4. CCC
-
I was wondering if there's some technical/political reason not to include both Python 2.7 and 3.3. You could provide a switch in settings (set as default on 2.7)
-
@ccc It's mostly a manual process unfortunately, and as you're probably aware, I'm a little behind with the Python releases, but I hope to get 2.7.4 integrated relatively soon (not while it's still a release candidate though).
@lucasoldaini That's technically not possible. One of the restrictions of iOS apps is that everything has to be a single binary. Compiling multiple versions of Python into a single binary would lead to lots of duplicate symbols etc.
-
The three releases are now final on python.org
-
@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 v1.3UPDATE: 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.
