Python 3. OS/X 10.6 Ipython
by John Riordan April 9, 2011

April 9, 2011

I am trying to get IPython running with Python 3.1 on OS/X 10.6.3. The install script for IPython configures it to run with Python 2.6. Is there a way around this?

PytDev intro documentation review?
by richard k belew Jan. 1, 2011

Jan. 1, 2011

i'm getting ready to teach a Python-based intro programming course, and i've committed to a development stack leading to PyDev on Eclipse. (yes, my sanity has already been questioned.) if this class is like most others, most kids will come in with Windoz laptops, but some with Macs, and (long shot) maybe even a Linux user or two. So i've written up some instructions for getting their environments put together, at: http://cogs18.edurik.org/syllabus/resources/installation-of-python-eclipse-… i'm wondering if members of this experienced list might give it a read and see if they can suggest any sources of confusion i might avoid? in particular, if you look at http://cogs18.edurik.org/syllabus/resources/installation-of-python-eclipse-… Item#3 has to do with the Mac install of Python. here i lay out two alternatives, one using the standard system installed Python and the other installing the standard Python release. since my ultimate goal is to simply get the PyDev plugin for Eclipse operational, and PyDev says it'll work with any Python >= 2.1, this SEEMs safe. do y'all agree? any other suggestions? the students-to-come thank you!

py2app w/ setuptools
by matgeek＠gmail.com Dec. 30, 2010

Dec. 30, 2010

Hi Everyone, I've been playing around with py2app for the last few days, trying to assemble Deluge 1.3.1 <http://dev.deluge-torrent.org/wiki/About> (a rather large python/gtk project that links against the C++ project *libtorrent*) into an .app and I'm at the point now where I should probably verify that what I'm attempting to do is actually possible, before spending several more hours pounding my head against my monitor. I have a few years of *nix experience and a small amount of programming background, but I'm certainly not a unix power-user by any stretch of the imagination - this is proving to be a limiting factor in my journey so far. I'm not sure that I'm fully understanding the specifics, so forgive me if the following sounds ridiculous. I have installed Deluge via MacPorts using this command: "*sudo port install boost +python26 pango +no_x11+quartz cairo +no_x11+quartz gtk2 +no_x11+quartz libnotify +no_x11+quartz deluge*"... Which gets Deluge up and running, so I know at least the dependcies have been satisfied. After a little digging, I've come to realize that it's being run by setuptools, which is where things get a little foggy for me. The file that is called, which opens Deluge, is not an executable unix file, nor does it have a python file extension. It's simply called 'deluge' - the contents of which are: #!/opt/local/Library/Frameworks/Python.framework/Versions/2.6/Resources/Python.app/Contents/MacOS/Python # EASY-INSTALL-ENTRY-SCRIPT: 'deluge==1.3.1','gui_scripts','deluge' __requires__ = 'deluge==1.3.1' import sys from pkg_resources import load_entry_point > if __name__ == '__main__': sys.exit( load_entry_point('deluge==1.3.1', 'gui_scripts', 'deluge')() ) My assumption is that this file is where setuptools is working it's magic, but it leaves me completely stumped as to which file I should be passing into py2applet (and ultimately py2app). Since that left me stumped, I thought I'd try to create an .app from the Deluge source code (not the installed, running version - just an extracted tar ball). I first renamed the setup.py included in the source to Deluge.py and issued "py2applet --make-setup Deluge.py" followed by "python setup.py py2app -A". But the resulting .app is created way too quickly to be legit and when I attempt to run it I get the following output: Traceback (most recent call last): File > "/Users/mat/Coding/Deluge/python/deluge-1.3.1/dist/Deluge.app/Contents/Resources/__boot__.py", > line 164, in <module> > _run(('\x00\x00\x00\x00\x01\x1e\x00\x02\x00\x00\x04iMat\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\xc6Y\xdb\xecH+\x00\x00\x00\xe5\xcd\xf3\tDeluge.py\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\xf4ua\xc9As\xa2\x00\x00\x00\x00\x00\x00\x00\x00\xff\xff\xff\xff\x00\x00I > \x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x10\x00\x08\x00\x00\xc6Z\x06\x1c\x00\x00\x00\x11\x00\x08\x00\x00\xc9A\xab\xe2\x00\x00\x00\x0e\x00\x14\x00\t\x00D\x00e\x00l\x00u\x00g\x00e\x00.\x00p\x00y\x00\x0f\x00\n\x00\x04\x00i\x00M\x00a\x00t\x00\x12\x005Users/mat/Coding/Deluge/python/deluge-1.3.1/Deluge.py\x00\x00\x13\x00\x01/\x00\x00\x15\x00\x02\x00\n\xff\xff\x00\x00', > '/Users/mat/Coding/Deluge/python/deluge-1.3.1/Deluge.py')) File > "/Users/mat/Coding/Deluge/python/deluge-1.3.1/dist/Deluge.app/Contents/Resources/__boot__.py", > line 160, in _run execfile(path, globals(), globals()) File "/Users/mat/Coding/Deluge/python/deluge-1.3.1/Deluge.py", line 29, in > <module> from setuptools import setup, find_packages, Extension File > "/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-packages/setuptools-0.6c11-py2.6.egg/setuptools/__init__.py", > line 2, in <module> File > "/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-packages/setuptools-0.6c11-py2.6.egg/setuptools/extension.py", > line 2, in <module> File > "/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-packages/setuptools-0.6c11-py2.6.egg/setuptools/dist.py", > line 5, in <module> File > "/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-packages/setuptools-0.6c11-py2.6.egg/setuptools/command/install.py", > line 2, in <module> File > "/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/distutils/command/install.py", > line 21, in <module> from site import USER_BASE ImportError: cannot import name USER_BASE My assumption now is that py2app needs to be run against the installed, running version in order to track the various libraries that need to be bundled in the final .App - but perhaps I'm incorrect here?

Popen and py2app
by Adam Morris Dec. 28, 2010

Dec. 28, 2010

py2app experts, I have a script that is packaged using and py2app that does a pre-check to see if a command line utility is installed, using Popen and "which name". (The script downloads and installs it if not.) I pass subprocess.PIPE for stdout and stderr, with shell=True. When I run the script "raw" from the terminal it always prints, correctly, with the path to the desired utility, i.e. ('/usr/local/bin/name', '') When I run the program after compiling with py2app, exactly as documented on the website, the console always gets ('', '') as the response, which is incorrect as it's definitely installed ... nor was an error reported. I even tried re-writing the Popen command as "/usr/bin/which name" to no avail. Using 10.6.5, py2app 0.5.2. Could this be a problem with py2app, or is there something about the run-time environment I've overlooked? Would also be interested if there is a better way of checking to see if a command line utility is currently located in the path for the current user's system. (Just a hobbyist here, go easy on me!) -Adam

Correct owner and group in python directory
by Vincent Davis Dec. 15, 2010

Dec. 15, 2010

Depending on how I instal modules into python I get different owner and group settings. Basically either I am the owner with the group being admin or root is the owner with admin group again. What is "correct" ideally. I as because I am working on a project to package some python modules into a installer/dmg and what to make sure they get installed with the right owner and group set. -- Thanks Vincent Davis 720-301-3003

Re: [Pythonmac-SIG] Accessing the iTunes database directly?

[Pythonmac-SIG] Accessing the iTunes database directly? David Stokes wrote: > Can the iTunes library database be accessed directly via Python? No. Your only options are the Apple event interface and the read-only XML file in your iTunes library. > What I want to do are some fairly basic manipulations of the data but using the scripting API (from both appscript and AppleScript) was ridiculously slow; operations that took seconds in comparable manipulations of a SQLite database of a similar size took multiple hours. Did you read the 'About application scripting' and 'Performance issues' chapters in the appscript manual? Remember, Apple events = RPC + queries, not OOP. Remotely iterating over large data sets will absolutely kill your script performance-wise. While certain tasks can only be done via iteration and lots of small simple commands, e.g. setting the name of every track in a 50,000-track library, plenty of others can be reduced to just one or two commands by using more sophisticated queries, e.g.: tracks_ref = iTunes.tracks info = zip(tracks_ref.name.get(), tracks_ref.album.get()) # 2 commands not: info = [(track.name.get(), track.album.get() for track in iTunes.tracks.get()] # 2*N+1 commands If you're already familiar with how relational DB queries operate, it's not so different (as that is where the original AppleScript engineers nicked half their ideas from).
