how to test get_special_folder_path()?
by Philip Semanchuk Sept. 29, 2010

Sept. 29, 2010

Hi all, The documentation for get_special_folder_path() and friends says that they're "available as additional built-in functions in the installation script". http://docs.python.org/distutils/builtdist.html#the-postinstallation-script Does anyone know of a way to play around with these functions outside of a post-install script? It's time-consuming to install something just to experiment with a single function. Thanks Philip

/proc/stat or /proc/uptime, depending. See the proc(5) man page.

sorry, my error; in order to achieve what written before, i had to link to the libpython2.6.a that i find downloading the surce code. instead, if I link to the one of the distributed version, i get the following error: missing required architecture x86_64 in file. i tried to build with the -m32 option,but then to that message, another is added for the object file file was built for i386 which is not the architecture being linked (x86_64) >----Messaggio originale---- >Da: tinauser(a)libero.it >Data: 29/09/2010 16.06 >A: <python-list(a)python.org> >Ogg: embedding python in macOS 10.6 > >hi there, > >i'm trying to embed python in a c++ code.i'm starting with the example in the >tutorial.i've problem with setting up the enveiroment. >I've installed python with the distributed version (i.e., i did not, as a >start, build it myself); i added the library where both python.h and pyconfig >are stored and i linked to libpython2.6.a (which is, in the distributed >version, an alias). >the program builds and links correctely, but if I try to run it, i get the >following error: > >Could not find platform independent libraries <prefix> >Could not find platform dependent libraries <exec_prefix> >Consider setting $PYTHONHOME to <prefix>[:<exec_prefix>] >'import site' failed; use -v for traceback >Traceback (most recent call last): > File "<string>", line 1, in <module> >ImportError: No module named time > >what is the problem? > >in my .profile i have set PATH: /Library/Frameworks/Python. >framework/Versions/2.6/bin

Python becoming orphaned over ssh
by David Sept. 29, 2010

Sept. 29, 2010

Hi there, I have a strange situation. If I do this: 1. Make a script /tmp/test.py on a remote server, with this contents: #!/usr/bin/python from subprocess import check_call check_call(['ping', 'www.google.com']) 2. Call the script like this over SSH: ssh root@testbox /tmp/test.py 3. Interrupt the script with Ctrl+C. Then what happens: The SSH session terminates, as expected. However: On the testing box, the Python script is still running, and so is the ping session. However, if I make an equivalent shell script, /tmp/test.sh, with this contents: #!/bin/bash ping www.google.com And then run it over ssh like this: ssh root@testbox /tmp/test.sh And then hit Ctrl+C, then the shell script and ping are both interrupted remotely, as expected. Here is how 'pstree -p' looks for the python script on the test box, before Ctrl+C: <init (1) up here> ├─sshd(1158)─┬─sshd(19756)───test.py(19797)───ping(19798) │ └─sshd(20233)───bash(20269)───pstree(19875) And after Ctrl+C: <init (1) up here> ├─sshd(1158)───sshd(20233)───bash(20269)───pstree(20218) ├─test.py(19797)───ping(19798) Basically, the server-side sshd sub-process has disconnected, but the Python script (and it's ping subprocess) have become orphaned, and now belong to the init process. Note, this only seems to happen if Python is executing a subprocess, and only while Python is being run through a non-interactive ssh session. How can I make Python behave better? I want it to close down itself and it's subprocess, and not orphan itself when I hit ctrl+C PS: The Python version on the testing box: 2.6.4, and the box itself is running Ubuntu Karmic. Also, it's not just ping, but other utilities, eg wget. PPS: I did also try adding logic to the python script, to keep an eye on all the ppids (parent, grandparent, etc), and then to interrupt itself and kill it's subprocess, but that doesn't seem to work: For whatever reason, Python seems to be unable to kill it's subprocess in this situation. The Python process closes, and ping becomes a child of init. But I can then kill ping manually, from a separate ssh session.

embedding python in macOS 10.6
by tinauser＠libero.it Sept. 29, 2010

Sept. 29, 2010

hi there, i'm trying to embed python in a c++ code.i'm starting with the example in the tutorial.i've problem with setting up the enveiroment. I've installed python with the distributed version (i.e., i did not, as a start, build it myself); i added the library where both python.h and pyconfig are stored and i linked to libpython2.6.a (which is, in the distributed version, an alias). the program builds and links correctely, but if I try to run it, i get the following error: Could not find platform independent libraries <prefix> Could not find platform dependent libraries <exec_prefix> Consider setting $PYTHONHOME to <prefix>[:<exec_prefix>] 'import site' failed; use -v for traceback Traceback (most recent call last): File "<string>", line 1, in <module> ImportError: No module named time what is the problem? in my .profile i have set PATH: /Library/Frameworks/Python. framework/Versions/2.6/bin

Hello, I have a list of list assume myList[x][y] is integer I would like to create an alias to that list which I could call this way: alias[y][x] returns myList[x][y] how can I do that ? (python 2.6) (I have a feeling I should use 'property' ;) Thanks, --

Introducing Kids to Programming: 2 or 3?
by Marco Gallotta Sept. 29, 2010

Sept. 29, 2010

Hi there I'm sure you get a lot of "2 or 3" questions, but here's another. Umonya [1] uses Python to introduce school kids to programming. The initiative is only 15 months old and up till now we've been using existing notes and exercises and thus Python 2. But we're at the stage where we can either stick with 2 for the next few years, or go to 3 now. We received a grant from Google to reach 1,000 kids in South Africa with our course in 2011. People have also shown interest in running the course in Croatia, Poland and Egypt. We're also eyeing developing African countries in the long-term. As such, we're taking the time now to write our very own specialised course notes and exercises, and we this is why we need to decide *now* which path to take: 2 or 3? As we will be translating the notes we'll probably stick with out choice for the next few years. Since these are kids, we feel the nice changes in 3 such as removing integer division will help in teaching. It will also remove confusion when they go to download Python and grab the latest version. Since they're just starting, chances are almost none will be hit by the limited library support for at least a year or two. They will, however, be hit by the confusion of seeing Python 2 code all over the web. We're tending towards 3, but I am a little cautious myself.
