Solaris, HP-UX and AIX builds, and access to older versions are available in ActivePython Business, Enterprise and OEM editions: http://www.activestate.com/python ActivePython includes the Python core and the many core extensions: zlib and bzip2 for data compression, the Berkeley DB (bsddb) and SQLite (sqlite3) database libraries, OpenSSL bindings for HTTPS support, the Tix GUI widgets for Tkinter, ElementTree for XML processing, ctypes (on supported platforms) for low-level library access, and others. The Windows distribution ships with PyWin32 -- a suite of Windows tools developed by Mark Hammond, including bindings to the Win32 API and Windows COM. ActivePython also includes a binary package manager for Python (PyPM) that can be used to install packages much easily. For example: C:\>pypm install mysql-python [...] C:\>python >>> import MySQLdb >>> See this page for full details: http://docs.activestate.com/activepython/2.6/whatsincluded.html As well, ActivePython ships with a wealth of documentation for both new and experienced Python programmers. In addition to the core Python docs, ActivePython includes the "What's New in Python" series, "Dive into Python", the Python FAQs & HOWTOs, and the Python Enhancement Proposals (PEPs).

Python 3.2rc1 available: new 10.6 IDLE and tkinter options
by Ned Deily Jan. 17, 2011

Jan. 17, 2011

The first release candidate of Python 3.2 is now available. As with Python 2.7.1, two variants of Mac OS X installers are available for this release: the traditional 32-bit-only installer that works on all machines supported by Mac OS X 10.3.9 through current 10.6.x ; and a new 64-bit/32-bit installer for OS X 10.6.x systems. Besides the operating system versions supported, one big difference between the two is in the versions of Tcl/Tk supported by IDLE and any other programs that use tkinter, the Tk GUI toolkit included in the Python standard library. As in previous releases, the 32-bit-only installer will use the Apple-supplied TK 8.4 available in OS X 10.4, 10.4, and 10.6, or, if installed, will use ActiveState Tk 8.4 (part of ActiveTcl). Up until recently including at 2.7.1 release, the only standard available 64-bit-capable Aqua Tk version was the Cocoa Aqua 8.5 version shipped by Apple in OS X 10.6; however that has proven to be problematic when used with IDLE and other tkinter apps. Recently, ActiveState has made available a newer version of Cocoa Aqua Tk (as of this writing, 8.5.9) which seems to have solved nearly all of the IDLE problems that have been reported when using Apple Tk 8.5. The Python 3.2rc1 64-/32-bit installer is the first python.org installer that supports using the new ActiveState 8.5. It will still fall back to the Apple version but IDLE will issue a warning in that case. Which variant should you use? For 10.5 and earlier, you can only use the 32-bit version. If you are on 10.6 and want the simplest out-of-the-box experience, you may want to stick with the traditional 32-bit-only installer. Also, if you need to build applications (for example, with py2app) that need to also run on older OS X systems, you should use this version. If you really do need 64-capabilities or if you would like to try out the improved GUI capabilities in Tk 8.5 and are willing and able to install the ActiveState Tcl/Tk 8.5, then you should consider installing the new variant. If you need to use IDLE or tkinter but cannot install the ActiveState Tk 8.5, you should not use the 64-/32-bit variant with 10.6 at this time (10.6.6). In either case, your testing and feedback is needed! Please try out either or both versions and report any issues as soon as possible to the python bug tracker, http://bugs.python.org, as the final release of 3.2 is less than a month away. http://www.python.org/download/releases/3.2/ Also, along with the release is a new web page attempt at consolidating information about supported Python, Mac OS X, and Tcl/Tk releases. It will be evolving up to and beyond the release. Your comments (via the bug tracker) on it are also encouraged. http://www.python.org/download/mac/tcltk/ Thanks!

Loading Python on my Mac
by John Parker Jan. 13, 2011

Jan. 13, 2011

Hello, I'm totally new to Python and having worked in a windows environment for years and now my personal pc of choice is a mac. Would someone be so kind as to walk me through installing python on a mac? I don't want to use the newest version because the class that I'm trying to get into uses 2.6 and 2.7 versions only. So, I need that version installed so I can do homework assignments, etc. Many thanks, John

py2app looking for ae.so in the wrong place

Jan. 9, 2011

I finally upgraded my iMac from 10.5 to 10.6 and tried to recompile one of my py2app apps with the system Python 2.6.1 and current py2app. The application uses appscript, but for some reason it's trying to import ae.so from /System: % dist/StreamVision.app/Contents/MacOS/StreamVision Traceback (most recent call last): File "/Users/nicholas/Documents/Development/StreamVision/dist/StreamVision.app/Contents/Resources/__boot__.py", line 31, in <module> _run('StreamVision.py') File "/Users/nicholas/Documents/Development/StreamVision/dist/StreamVision.app/Contents/Resources/__boot__.py", line 28, in _run execfile(path, globals(), globals()) File "/Users/nicholas/Documents/Development/StreamVision/dist/StreamVision.app/Contents/Resources/StreamVision.py", line 4, in <module> from appscript import app, k, its, CommandError File "appscript/__init__.pyc", line 8, in <module> File "aem/__init__.pyc", line 5, in <module> File "aem/ae.pyc", line 18, in <module> File "aem/ae.pyc", line 15, in __load ImportError: '/System/Library/Frameworks/Python.framework/Versions/Current/lib/python2.6/lib-dynload/aem/ae.so' not found 2011-01-03 21:23:47.306 StreamVision[82885:903] StreamVision Error ae.so is indeed in the app package: % ls **/ae.so dist/StreamVision.app/Contents/Resources/lib/python2.6/lib-dynload/aem/ae.so Any ideas what's going on here?

Escaping commandline strings
by Chris Weisiger Jan. 4, 2011

Jan. 4, 2011

I want to sanitize some strings (e.g. escape apostrophes, spaces, etc.) before passing them to the commandline via subprocess. Unfortunately I can't seem to find any built-in function to do this. Am I really going to have to write up my own sanitizer? Not that it'd be much effort, but I'd much rather use an official function than risk forgetting something. -Chris

made app using py2app, can't pass arguments properly

Jan. 4, 2011

Hi, I'm new to python/py2app. My original python script accepts arguments as such: python merge.py -o outfile.txt - i infile1.txt infile2.txt Once I create the .app from py2app using argv emulation this no longer works and I get the following feedback: new-host:dist Ian$ merge -o outfile.txt -i infile1.txt infile2.txt merge: unknown option: -o merge: usage: merge [-AeEpqxX3] [-L lab [-L lab [-L lab]]] file1 file2 file3 merge: too many arguments this is the setup.py that py2app generated automatically """ This is a setup.py script generated by py2applet Usage: python setup.py py2app """ from setuptools import setup APP = ['merge.py'] DATA_FILES = [] OPTIONS = {'argv_emulation': True} setup( app=APP, data_files=DATA_FILES, options={'py2app': OPTIONS}, setup_requires=['py2app'], ) Any idea what I'm doing wrong? Thanks in advance!

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!
