If you have ever looked at your Mac?s root directory and wondered what
some of those other directories are for, you?re probably not alone.
Mac OS got a whole lot more complex with the advent of OS X, adapting
a unix file structure from Free BSD Unix that is largely unfamiliar to
Mac OS 9 and Windows users.
It should be added that it looks very unfamiliar to Unix users too,
if your list below is correct.

The installer should update your $PATH environment variable to put the newly
installed python executable before the system's if you use the bash shell. For
example, it added this to my ~/.bash_profile file:
# Setting PATH for MacPython 2.5
# The orginal version is saved in .bash_profile.pysave
PATH=/Library/Frameworks/Python.framework/Versions/Current/bin:${PATH}
export PATH
If you use a different shell, you may need to edit the appropriate file to add
the above to the $PATH.

Re: Upgrade Python on a Mac
Thank you Robert. Since I'm using a ~/.profile file instead of a
~/.bash_profile file, I guess the installer didn't update it. I just
updated the path like you mentioned and now the new version of Python
comes up.

as you know, the framework pythons go into:

f you have ever looked at your Mac’s root directory and wondered what
some of those other directories are for, you’re probably not alone.
Mac OS got a whole lot more complex with the advent of OS X, adapting
a unix file structure from Free BSD Unix that is largely unfamiliar to
Mac OS 9 and Windows users. So just what is /System, /Library, /usr,
and all the others for anyway? Here’s a brief explanation of each
directory as found in Mac OS X.
By default, if you look in the root of your Mac’s hard disk you’ll see
some unfamiliar sounding directories. From the command line, you will
see even more if you type ls /. Explained in no particular order:
/Applications = Self explanatory, this is where your Mac’s applications are
kept
/Developer =The Developer directory appears only if you have
installed Apple’s Developer Tools, and no surprise, contains developer
related tools, documentation, and files.
/Library = Shared libraries, files necessary for the operating system
to function properly, including settings, preferences, and other
necessities (note: you also have a Libraries folder in your home
directory, which holds files specific to that user).
/Network = largely self explanatory, network related devices, servers,
libraries, etc
/System = System related files, libraries, preferences, critical for
the proper function of Mac OS X
/Users = All user accounts on the machine and their accompanying
unique files, settings, etc. Much like /home in Linux
/Volumes = Mounted devices and volumes, either virtual or real, such
as hard disks, CD’s, DVD’s, DMG mounts, etc
/ = Root directory, present on virtually all UNIX based file systems.
Parent directory of all other files
/bin = Essential common binaries, holds files and programs needed to
boot the operating system and run properly
/etc = Machine local system configuration, holds administrative,
configuration, and other system files
/dev = Device files, all files that represent peripheral devices
including keyboards, mice, trackpads, etc
/usr = Second major hierarchy, includes subdirectories that contain
information, configuration files, and other essentials used by the
operating system
/sbin = Essential system binaries, contains utilities for system administration
/tmp = Temporary files, caches, etc
/var = Variable data, contains files whose contents change as the
operating system runs
