Unable to run python application (beegee beegee)
by Dan Ross April 15, 2009

April 15, 2009

Hi bee gee - You need to type "python first.py" into Terminal, not IDLE.

Hi, you can run your program from the terminal.app (Application -> Utility -> Terminal.app) simply running : python /path/to/first.py if you want run it inside a python shall, you need to define a function, to do it : changes the code to : #|/usr/bin/python def first(): print " Hello world" user_input = raw_input("What is your name?") print "Thank you", user_input then open terminal.app cd /directory where is your file.py type python macbook-pro-15-di-sasha:Desktop sasha$ python Python 2.5.1 (r251:54863, Jan 13 2009, 10:26:13) [GCC 4.0.1 (Apple Inc. build 5465)] on darwin Type "help", "copyright", "credits" or "license" for more information. >>> from first import * >>> first() Hello world What is your name?epi Thank you epi >>> Massimo Di Stefano massimodisasha(a)yahoo.it epifanio on irc.freenode.net /join gfoss Il giorno 15/apr/09, alle ore 20:38, pbeegee beegee <beegee63(a)gmail.com> ha scritto: > > > > Hi there, I am a beginner in python and I wrote a simple program > called first.py (using aquamacs) and stored it on my desktop. > I opened IDLE and wrote the command python first.py > and I got a syntax error with 'first' being highlighted > I have a mac os 10.4.11, python 2.6.1 on IDLE > and I also used the aquamacs compiler for python > /* the program i wrote was*/ > print " Hello world" > user_input = raw_input("What is your name?") > print "Thank you", user_input > */ > <first.py><Picture 1.png><Picture 2.png> > Chiacchiera con i tuoi amici in tempo reale! http://it.yahoo.com/mail_it/foot/*http://it.messenger.yahoo.com

py2app path question
by Shane Clements April 15, 2009

April 15, 2009

Hi. Looking for advice about p2app and paths during the bundling process. The application I am working with works fine finding the paths before being bundled with py2app but after has mangled ones. An example error: IOError: [Errno 2] No such file or directory: '/Users/Shane/UTc!/client/dist/client.app/Contents/Resources//Users/Shane/UTc!/client/dist/client.app/Contents/Resources/assets/objects/ships.xml' What is looks like is py2app is making aliases perhaps...? Is there a way to avoid this? Thanks, Shane

Official 'right way' to create a universal build of Python?
by Mark Dickinson April 14, 2009

April 14, 2009

This question has probably been asked and answered before, but I've failed to find anything in the archives. What's the 'correct' way to create a universal build of Python? Specifically, I have two machines: (1) a Macbook Pro (Core 2 Duo) running OS X 10.5, and (2) an iBook G4 running OS X 10.4. and a fresh checkout of the py3k branch from svn.python.org. I have a fairly limited goal: I want to create a universal (32-bit Intel/32-bit PPC) build on the 10.5/Intel machine, transfer it to the 10.4/PPC machine and then run the testsuite. (This has to do with making sure that a planned checkin is compatible with universal builds; see the (long) thread at http://mail.python.org/pipermail/python-dev/2009-April/088417.html ). What are the commands that I should execute on the Macbook? I tried: ./configure --with-universal-archs=32-bit --enable-framework --enable-universalsdk=/ MACOSX_DEPLOYMENT_TARGET=10.4 && make This seems to give me the right thing: Macintosh-4:py3k-short-float-repr dickinsm$ file python.exe python.exe: Mach-O universal binary with 2 architectures python.exe (for architecture ppc): Mach-O executable ppc python.exe (for architecture i386): Mach-O executable i386 Having done this, how do I package things up to transfer them to the iBook? What files need to be transferred? Mark

Getting None in KVC objectInKeyAtIndex_
by David Hain April 14, 2009

April 14, 2009

I'm trying to use bindings to hook up my model to an NSOutlineView, and I'm attempting to use the countOf<Key>, objectIn<Key>AtIndex_ methods to do the KVC half. The problem I'm running into is that I'm getting None for the index argument, and I can't figure out what to do with that. The reference materials[1] say that the method corresponds to the NSArray objectAtIndex: method, which takes an NSUInteger, but doesn't mention anything about null or nil or whatever it is in objc- land. So the question is, is the view supposed to be giving me None for that argument, or did I hook something up in IB (or elsewhere) incorrectly? If None is expected, then how am I supposed to interpret that? What should I return? Here's a paraphrase of my model: class Node(NSObject): ... def countOfChildren(self): return len(self.children) def objectInChildrenAtIndex_(self, index): return self.children[index] If other information or code would be helpful, I'd be happy to provide it. Thanks! -David [1]: http://developer.apple.com/documentation/Cocoa/Conceptual/KeyValueCoding/Co…

Virtual Serial/USB Port
by Stuart Davenport April 11, 2009

April 11, 2009

Hi all, I am trying to write a python program to "emulate" a USB GPS device on my Mac, is there anyway this is possible via Python? Basically I have something running over the network to tell my Mac its GPS location. The application I have running is listening to the data from the network and then I want that data be pushed onto a "virtual" USB GPS device. The data I will send out of it will be the standard NMEA data for any navigation software on a Mac (e.g. RouteBuddy) to read. Would anyone know how to create this "virtual port" through python? Thanks Stu

Problem with py2app and pygame on OS X Leopard (10.5.6)
by Michael Sanders April 11, 2009

April 11, 2009

I can't seem to get py2app to work with pygame. I'm testing by just trying to compile a simple hello world app: . > '''A simple app that displays "Hello, world!" the title bar of its > window.''' import pygame > quit = False pygame.init() screen = pygame.display.set_mode((640, 480)) pygame.display.set_caption('Hello, world!') > while not quit: pygame.event.pump() for event in [pygame.event.wait()] + pygame.event.get(): if event.type == pygame.QUIT: quit = True I ran py2applet --make-setup hello_world.py to make the setup.py, and it looks like this: """ This is a setup.py script generated by py2applet > Usage: python setup.py py2app """ > from setuptools import setup > APP = ['hello_world.py'] DATA_FILES = [] OPTIONS = {'argv_emulation': True} setup( app=APP, data_files=DATA_FILES, options={'py2app': OPTIONS}, setup_requires=['py2app'], ) Running "python setup.py py2app" now seems to work fine with no errors, however, when I run the app I get this error message: hello_world Error "An unexpected error has occured during execution of the main script ImportError: PyObjC 1.2 or later is required to use pygame on Mac OS X. > http://pygame.org/wiki/PyObjC (Leopard comes with PyObjC 2.0 and I haven't uninstalled it.) If I run "python setup.py py2app -A", I get: hello_world Error "An unexpected error has occured during execution of the main script ImportError: No module named pygame Any ideas on how to fix this? This app runs fine on my machine by running "python hello_world.py", and py2app seems to work with another test app I tried using pyglet.

Using Python with Emacs
by Gregg Lobdell April 9, 2009

April 9, 2009

How do I get Emacs to start the latest version of Python? I'm using "GNU Emacs 22.0.50.1 (powerpc-apple-darwin8.2.0) of 2005-08-06 on quartet.local" (as reported by M-x emacs-verion) on a PowerPC G5 running Mac OS X version 10.4.11 (yes I know I'm not running 10.5) The default Python version that came installed with 10.4 is Python 2.3.5 (#1, Jan 12 2009, 14:43:55), and I'd like to run Python 3.0. How can I convince Emacs to run 3.0 instead of the default 2.3? I've tried setting PYTHONPATH in my .cshrc, .login, and .emacs. My .cshrc adds /Library/Frameworks/Python.framework/Versions/3.0/bin to the PATH, but (getenv "PATH") in emacs returns "/usr/bin:/bin:/usr/sbin:/ sbin:/usr/local/bin:/usr/X11R6/bin" I can get it to start python 3.0 if, in python.el, I set python- python-command to "/Library/Frameworks/Python.framework/Versions/3.0/ bin/python". But this seems like a kludge, to have to set the full path. There must be a better way. After I did get python 3.0 to start, then I had to fix a bunch of stuff in emacs.py, mostly parens for print commands and converting tabs in the indentation to 8 spaces.

using the "PyUSB" module
by Rekow Warren April 7, 2009

April 7, 2009

I am a new MacPython (ver 2.6.1) user who has downloaded the "PyUSB" module, but am unclear about how to make it available for use in a program. Included among the downloaded files is 'setup.py' (and 'setup.pyc'). Running 'setup.py' via IDLE yields the following error msg: --- Traceback (most recent call last): File "/Applications/Python 2.6/pyusb-0.4.1/setup.py", line 62, in <module> ext_modules = [usbmodule]) File "/Library/Frameworks/Python.framework/Versions/2.6/lib/ python2.6/distutils/core.py", line 140, in setup raise SystemExit, gen_usage(dist.script_name) + "\nerror: %s" % msg SystemExit: usage: setup.py [global_opts] cmd1 [cmd1_opts] [cmd2 [cmd2_opts] ...] or: setup.py --help [cmd1 cmd2 ...] or: setup.py --help-commands or: setup.py cmd --help error: no commands supplied --- It seemed that 'setup.py' should be run in order to access functions in the PyUSB module, but perhaps I misunderstand the process. It would be appreciated if someone could suggest a related reference to read. Thanks, Warren

mactypes Alias/File object question
by Jeffery Beeland April 6, 2009

April 6, 2009

Hey gang, New to the list and mostly a Perl developer, so please excuse my lack of knowledge at this point. ;) I'm using appscript to interface with Photoshop, which has gone pretty well to this point. The problem is that I can't seem to find a way to get a posix path out of an Alias or File object from mactypes. As best I can tell there are no public methods for the classes. This becomes a problem when I want to query a list of open documents and expect to be able to get at the actual file path for something like display of file information in a UI component. I'd really hate to have to parse the file path out of the stringified object. I would greatly appreciate any advice any of you might have. --Jeff -- ____________________________ J e f f e r y B e e l a n d Lead Pipeline TD Rhythm + Hues Studios jbeeland(a)rhythm.com ____________________________ Excercision sounds like something you'd do to a zombie Richard Simmons.
