Python 3.4 will be supported with ArcGIS for Professionals

Does any know for certain which version of Python will ship with 10.3? Since it comes with ArcGIS for Professionals I thought it would be 3.4 but I haven't found any officials sources. Previous sources seemed to indicate ArcGIS 11 would be moving to 3.x but I'm not sure if this product release was renamed or that release was pushed back.

ArcGIS Pro (beta) is 3.4
ArcGIS 10.3 (development, not released) is 2.7.5. The only change that may happen between now and release is Python moving to 2.7.7, but I haven't heard discussion one way or another on this.

10.3 will not use 3.4. If you install each product on the same machine, they wont/cant use the other Python.

Kevin:

ArcGIS Desktop, which will stay at 32-bit with Python 2.7.x, can work and co-exist on a 64-bit machine with ArcGIS Professional with Python 3.4?

Re: Python in ArcGIS 10.3

KevinHibma — Tue, 10 Jun 2014 19:18:37 GMT

Yes.
I'm doing it right now.

Its really no different then having both ArcGIS Desktop 10.2.2 and 64bit Background Processing on the same machine.
You'll have 2 versions of 2.7.5 python: 32 and 64bit.

also note, ArcGIS Pro is 64bit, thus Python 3.4 64bit

Ah, so ArcGIS Pro and ArcGIS 10.3 are entirely independent platforms even at the backend? Requiring separate Python installs? Will the entire arcpy library be ported to ArcGIS Pro for release or will it have its own unique functionality? Is ArcGIS Pro going to be the default Python/geoprocessing environment or will that remain the regular Python 2.x/ArcGIS engine?

Hi Matthew,
10.3 will ship with Python 2.7, likely 2.7.7, but that could change depending on where Python is leading up to the 10.3 release date. We didn't want to make a break within the 10.x release line. Pro, on the other hand, will include Python 3.4.

For the most part, arcpy is largely moving forward to Pro intact. From 10.3 to Pro, the biggest difference will be to arcpy.mapping because of significant architectural difference between the two products. There will be a few other changes as well. There will be a new tool in Pro and 10.3 that will help people review their code and tools for these differences.

Dave, I missed last years user conference so I was wondering if there are any articles you can point us to that outline what's happening with ArcGIS Desktop? From what I've heard Desktop can't be upgraded to 64-bit so that's where Pro comes in? Does that mean Desktop will go away? But from whay I've quoted you on that our ArcGIS Desktop scripts will be able to run under Pro?

Sorry, I didn't want to hijack this theard but I'm confused on the future of Desktop.

Hi Randy,
Have a look at this Pro FAQ.

Will ArcGIS Pro be able to access data in either shapefile or personal geodatabase format? I could not tell from the above link whether this question is answered or not?

How about using lyr files generated in v10.3 to add data to ArcGIS Pro?

Re: Python in ArcGIS 10.3

KevinHibma — Fri, 13 Jun 2014 13:50:58 GMT

Shapefiles, yes.
pGDB, no. Pro is 64bit and has the same limitations* that ArcGIS Server and 64bit Background have.
*There could be minor exceptions to this rule that I'm unaware of.
Layerfiles (.lyr) can be imported into Pro. You cannot save a lyr file. Pro will save lyrx files which are not backwards compatible to 10.x

I'd encourage you to give the beta a try. If you still have questions after using it, thats important feedback we'd like to get and address if possible. If you're a named user you can download it from http://pro.arcgis.com/en/pro-app/#
(I'm unsure if there are any country restrictions)

Kevin:

When opening ArcGIS Professional Beta, it is asking for my ESRI organization account. Are these credentials going to be required when using this program in it's production version or is this just because it's in the Beta testing phase?

Where do we post comments about Beta software?

Re: Python in ArcGIS 10.3

KevinHibma — Mon, 16 Jun 2014 12:13:34 GMT

Michael,

Unsure about your license question.
I'd suggest posting to the beta forum. From the above link I posted to beta download, go there, and about half way down on the right is a "FORUMS" button. Someone with more knowledge on licensing should be able to help.

Re: Python in ArcGIS 10.3

MathewCoyle — Tue, 24 Jun 2014 12:10:55 GMT

Just an FYI that I had issues with and just got resolved. This requires you to use your admin ArcGIS Online account, NOT your ArcGIS license admin account.

What version of numpy will be installed with ArcGIS Pro and will python be installed in a separate directory (i.e. C:\Python34)?

Re: Python in ArcGIS 10.3

JasonScheirer — Fri, 27 Jun 2014 21:22:10 GMT

Python is an optional install in Pro App. If you don't download/install the Python for ArcGIS Pro package, Python will only be available from within the Pro App (it contains a Python runtime, not a full installation).

Right now Pro App is at NumPy 1.8.0, I believe it'll be updated to the most recent version before Pro App's release date.

The Python for Pro App installer will do what you expect it to do: it will install by default to C:\Python34\ (not C:\Python34\Desktop10.X\ like in previous versions).

Hi Kevin, is that option for importing layer files (*.lyr) 100% compatible, and especially will the display of all feature symbolization and feature labelling be 100% the same in both ArcGIS for Desktop and Pro? It is a real nightmare for cartographers to have to redesign loads of layer files, so it is vital to have truly good compatibility and transfer of properties to the maximum extent possible.

Marco,
I don't have that detailed information. You best way to get these questions answered is to:
1) Get involved in the beta (with the links posted previously)
2) Direct Pro specific questions to the Pro beta forums.

My understanding from Esri reps is that 10.x will continue to use Python 2.7.

Confirmed ArcGIS Pro will use Python 3.4:

Python 3 migration—ArcPy Get Started | ArcGIS for Professional

(With most current build as at writing)

Installation dir is quoted as C:\Python34, which sounds more like a full installation than a runtime (per Jason Scheirer‌), but in practise it is not there and is installed as ArcGIS Pro\bin\Python. There is no python.exe which seems to support Jason's comment.

Numpy version included is 1.8.0

Re: Python in ArcGIS 10.3

KevinHibma — Tue, 30 Sep 2014 13:15:43 GMT

Jason Scheirer‌ comments are correct.

Python is an optional install. If you don't install full Python installation, there will be "Python runtime" version where you've referenced (ArcGIS Pro\bin\Python). There is no exe for you to use in this case that, and you will only be available to use Python from within the app.

The full installation will be at c:\Python34 and includes the python.exe

This is a great thread, had a lot of info I was wondering about. I have a further question though. There were a couple of small differences in the way tool parameters were implemented between 10.0 and 10.1/10.2, specifically the way multivalue parameters were handled using the GetParameter... method. (Used to be they were acquired as valuetables, which was a little cumbersome.) I have a toolbox I wrote for 10.0 which I just upgraded to work with 10.1/10.2. I assume that all of the code itself will be compatible, but are there any small differences (like the multivalue parameter) between how scripts and tools will work in 10.1/10.2 and 10.3?
