Python On Mac

I need to write lots of Python on my MacOs X IBook...

I really want a Folding Text Editor On Mac

some other Mac-specific notes:

• if reading/writing log files on multiple platforms, use 'rU' in file-open call for universal-endLine

• pickle files don't seem to be supported across platforms - made one on MsWindows then copied it over, and when I tried to read it I got an "insecure string pickle" error message. Re-generated the pickle file locally and it worked fine.

• notes on upgrading

Feb'2006 notes

Tried doing build with Fink Commander, but that didn't work.

Installed Mac Python 2.4 for upgrade. Deleted the 2.3 folder from '~/Applications'

Easy Install (piece of Setup Tools)

• instructions turned out to have typo (at least for me) - little disutils.cfg file you make needs a '/' between the Python and the '$py_version_short'

• hmm, it's still using Python 2.3 when it tries to install!

  • when I just launch Python from the command line, I see from the startup lines that it is still running v2.3. In fact, is it too old to even work with Setup Tools? Python 2.3 (#1, Sep 13 2003, 00:49:11)

  • then I see {{{ Installing easy_install script to /System/Library/Frameworks/Python.framework/Versions/2.3/bin error: /System/Library/Frameworks/Python.framework/Versions/2.3/bin/easy_install: Permission denied}}}

Hmm, what various directories/folders do I have for Python?

• /Library/Frameworks/Python.framework/Versions/ contains '2.4' (and Current) not '2.3'; '2.4' contains bin, lib, include, etc.

• /System/Library/Frameworks/Python.framework/Versions contains '2.3' not '2.4' - aha!

• /Library/Python/ contains only '2.3' which contains bunch of standard stuff like site-packages, wx, waste, etc.

• ~/Library/Python/ contains only /IDE-Scripts/ directory

• ~/Library/ doesn't contain Frameworks

I notice that my Mac Python 2.4 is an "official unofficial" version which makes me a bit nervous....

Or maybe some of this stuff is messed up because I need to restart! So that's next...

• nope, that didn't help.

Maybe I need to figure [out](http://developer.apple.com/documentation/Mac O S X/Conceptual/B P Runtime Config/index.html) where the Environmental Variable-s are set, so I can use 2.4

• hmm, the environment.plist doesn't include anything relevant, and the other files don't seem to exist.

(then copying /Library/Python/2.3 to 2.4 ? renaming it? then deleting the /System/.../2.3/ directory?)

Tried deleting the key 2.3 directory, renaming another to 2.4; realized that the 2.4 just didn't include some things that were needed. Which led to.....

April'2006 notes

See new "universal" installer with special Mac binary. Download/install that.

• remove older 2.4 folder from Applications folder; run Update Shell Profile.command

• type python at command-line, launches and says it's running 2.4.3

• try double-clicking on IDLE icon, on launch get "quit unexpectedly" message::

Exception: EXC_BAD_ACCESS (0x0001) Codes: KERN_PROTECTION_FAILURE (0x0002) at 0x00000000

Going to go on with non-GUI stuff and see what happens...

Move on to Python Paste (Apr'2006-Feb'2007)

Then (Feb-Oct'2007) onto Robaccia.

Feb'2008: note some changes associated with moving to new MacBook/Leopard.

Apr'2008: time to move to Google App Engine? dunno
