Windows allows us to uninstall it. I think the only thing it really
installs is the files, and then it sets the system path, so just
delete the files and change your path. Unfortunately, I do not have a
Mac to test with.

I don't know if this is pertinent to your situation, but yesterday I
read something that said you need a "framework" install in order to do
GUI programming with wxPython. I believe a framework install is what
originally comes with Macs and it is integrated into the OS. I don't
know if there is a framework install for 2.5.

In addition, the download notes for the stand alone MacPython 2.5
install say that there aren't as many modules for 2.5 as there are for
the 2.4, which is something you may want to consider.

Did 2.4.4 come pre-installed?

Don't do it. OSX uses the shipped version for its own purposes, and
you'll break things if you uninstall it.

You're not required to remove the old version before installing the new version.

Just install the new version somewhere like /usr/local and put
/usr/local/bin ahead of your other paths.

That is exactly what I did. I don't touch the Apple supplied version.
Now I want to put that latest Python on.

No, the OSX version is like 2.3 something. I installed the 2.4.4
version in /usr/local bypassing the Apple stuff.

Can you explain how that works? If you install python in /usr/local,
doesn't that leave you with something like /usr/local/python? So what
does putting usr/local/bin ahead of your other paths do?

../configure --prefix=/usr/local

Then python would be /usr/local/bin/python.

For bash put this somewhere near the end of your .bashrc or /etc/bashrc:

export PATH="/usr/local/bin:$PATH"

Then when you attempt to run the python binary it will be found in the
place you installed it first, not where the system version was
installed.

When you install with --prefix==/usr/local you will wind up with
/usr/local/bin/python. There will also be a /usr/local/lib/pythonX.Y (with
structure underneath it) containing all the Python and extension modules.

You don't have to uninstall 2.4.4 to use 2.5. Just change where the
symlink points:

shanegeiger@sha ne-geigers-computer:~\ 14:45:35$ ls -la /usr/bin/python
lrwxr-xr-x 1 root wheel 24 Mar 1 12:48 /usr/bin/python ->
/usr/local/bin/python2.5
shanegeiger@sha ne-geigers-computer:~\ 14:45:40$

In general, I am a little wary of uninstalling programs like Python
which are used by many applications. You don't want to find out after
you have uninstalled it that something actually needed it. It is much
safer to keep it around.

I have been chastised on this list for a similar suggestion (notably
re-linking /usr/bin/python) as it may break the system because the
particular version installed may be required for some scripts in the system.

Probably better is to create a link in ~/bin and make sure ~/bin is
first in the path. Bash experts--please say how to do this because bash
is default for OSX and is undoubtedly what the OP is using. I use csh.

Better, even than this is to install ipython under 2.5 and put the
following script in your ~/bin (name it python):

#! /bin/csh -f
#second line of script (include above)

if ($#argv == 0) then
/usr/local/bin/ipython # <==or wherever ipython is
else
/usr/local/bin/python2.5 $argv
endif

#end of script

It doesn't matter if you use bash, the above script, though csh, will
run fine.

Now type this in a terminal: "chmod a+x ~/bin/python".

Now you can use ipython or python depending on whether you supply
arguments. ipython will launch if you supply none (which means you want
an interactive interpreter) and "regular" python2.5 will launch if you
give it a script name--avoiding jumping into the ipython interpreter
after the script finishes.

If you don't know what ipython is, you are missing out.

Don't build python for OS X unless you know you need to or want a
learning experience. Rolling your own python is somewhat a can of worms
for the uninitiated and it will be pretty tough beyond that to make it
run as cleanly as the stock builds. (E.g. you will be asking about why
readline doesn't work, etc.) This stuff is especially the case for OS X,
which does things a little differently than linux.

Just download the 2.5 installer from python.org. Double click it and be
done. A link to the new python will be created for you in
/usr/local/bin. If you already had an earlier installed and the link
didn't get updated, just replace the old one substituting 2.4 (or 2.3)
with 2.5.

Then make sure /usr/local/bin comes before /usr/bin in your path and you
will be set. See also my previous post about integrating ipython.

Don't uninstall it.

That's why Apple put python under /Library/Frameworks/
Python.framewor k/Versions. So you can have multiple versions installed.

Hopefully you left Apple's default install of 2.3.5 unmolested as
well. My best advise is to download the binaries from python.org and
install. This gives you a nice universal framework build, compete
with readline support.

If you do elect to build it yourself, just make sure to read the Mac
specific documentation (which tells how to generate a framework
build). Whichever route you take, /usr/local/bin/python and /Library/
Frameworks/Python.framewor k/Versions/Current/bin/python will point to
pyhon2.5. Since you already have 2.4x I assume your path already
contains /usr/local/bin -- otherwise, you'll probably keep picking up
the default 2.3.5 in /usr/bin.

It looks like Stackless has a Mac binary install as well. Does
anybody here know if I can install that on top of a stock 2.5 without
breaking things?

Michael
