I just purchased a new macbook (os 10.4.6), and I'm trying to install
python 2.4 on it. I downloaded and ran the two installers recommended
at http://www.python.org/download/mac/. Now I have IDLE, which runs
2.4.1, but typing "python" at a terminal still opens 2.3.5, because it
points to /usr/bin/python. Is there a way to run python 2.4 without
idle? If I want to do a unix style script, something like
#!/usr/bin/python
print "hello world"
what can I put on the first line that will cause python 2.4 to
interpret my code?
Thanks a lot.

The python in /usr/bin is a link (to a link). You can do this:
sudo rm /usr/bin/python
sudo ln -s \
/System/Library/Frameworks/Python.framework/Versions/2.4/bin/python \
/usr/bin/python
This stupid firebird editor word-wraps (and I don't know how to turn
this completely annoying behavior off. Appearantly this is because it is
impossible to soft wrap text on the reader side, annoying NNTP veterans
everywhere--we just can't count on this hard to program behavior in most
mail readers because its so impossible to program for. Its been this way
since reader-client word wrapping was predicted to exist at MIT in the
1970's.) so get a unix guru to help you with that last command if you
really don't know what's going on.

There is no 2.4 in my Versions folder, only 2.3 and current. Should
one of the installers have created this directory? Which one?

Darn, that page needs to be fixed -- it's out of date!-( Sorry...
See instead <http://www.python.org/download/releases/2.4.3/> and
download
<http://www.python.org/ftp/python/2.4.3/Universal-MacPython-2.4.3.dmg>,
you should be much happier.

Thanks to you both. I downloaded the dmg suggested, and trustingly
typed:
sudo rm /usr/bin/python
sudo ln -s /usr/local/bin/python2.4 /usr/bin/python
And now my command line and scripts behave the way I expect. Thanks
again.
THN
You removed /usr/bin/python! This is a really bad idea. You should
never modify /usr/bin because the system is expecting it. This is why
the new installation is in /usr/local/bin.
Modify your /usr/local instead are change your .login file instead. It
is much safer.

sudo rm /usr/bin/python sudo ln -s \ /System/Library/Frameworks/Python.framework/Versions/2.4/bin/python \ /usr/bin/python
No, for the love of all that is holy, don't do that! OS X depends on stuff in
/usr/bin/. Don't pull the carpet out from under your OS!
The python executables from the Python 2.4 installer are installed to
/usr/local/bin/. I believe that the Universal binary that Alex linked to takes
care of adjusting the PATH environment variable such that this is exposed.

YIKES! Don't do that. Don't mess with Apple's python. Not
recommended. Check the MacPython FAQ and Wiki pages. Python 2.4 was
installed in /usr/local/bin. You should put that in your $PATH variable
Before /usr/bin. That will cause the new Python to be launched.

some afterthoughts:
- look at Oreilly's "OS X Tiger for Unix Geeks" before you do anything
that'll break OS X. Just in case you get the idea to upgrade the perl
that OS X installed, don't remove the one in /usr/bin either.
- investigate the Activestate disk image for OS X/Intel. I say
"investigate" cause i don't have any experience with OS X/Intel, but
the Activestate releases i've used for Windows and OS X in the past
have all been very high quality.
Well, as I stated in post, I've already replaced the link at
/usr/bin/python. I'm not clear why that's unhealthy. Should I change
it back to whatever it was before? I guess maybe it was
/System/Library/Frameworks/Python.framework/Versions/Current/bin/python
?
Thanks,

Ok, I fixed my /usr/bin/python and added /usr/public/bin/ to my PATH in
..profile. Everything seems ok now.
Thanks again to everyone for their help.

There's a free 3rd party tool known as Pacifist to extract part-installs
from Apple's system DVDs, but I'm not sure how you'd apply it to Apple's
Python -- try asking around on the Pacifist mailing list or site...

Never heard of one, but you should double-check on Macintosh-related
groups, where you're more likely to find relevant expertise.
