We learn something new everyday. When we stop learning we stop growing. Stop
growing and you are as good as dead (-: The book I linked to should really help
you on this journey. GUIs are very useful but sometimes getting your hands dirty
on the command line is a good thing. (-:

yes, that is what I meant.

Typically, if a python library package is tied to a specific python version the
version will be in the package name. For instance idle-python2.4 and
idle-python2.5. Otherwise, the package will install into a generic python
accessible location and be available to all version of python installed. Look at
/usr/lib and /usr/share. You should see multiple directories with the word
'python' in their name. Digging through their contents should make things more
clear.
I have never played with easy_install, so I can not comment on how that would
interact with prebuilt Ubuntu packages. I usually use Debian's unstable version
aka Sid. unstable in this case is the scientific definition meaning often
changing and not the more common usage of might break at any moment (-:
One more helpful tip. Go to the python.org website. There is a mailing list
there
called 'python tutor'. It is meant for all kinds of Python newbie questions --
ask about code, ask about packages, whatever. The people on the list have been
there for quite a few years and will be very careful to explain things (-: Just
the archives from that list may be helpful to you, depending on how you learn
new
things.
