Got me already ;')  I reinstalled Py2.7 since there are too many things not
available yet for Py3.3 - but I know which one is loading at the command
line since I specify Python2.7 or Python3.3 (The Activestate dist copies
and renames one of the Pys so that's clear - I just went and copied and
renamed the other - along with pip)  My IDE startup script has been changed
to also go to the proper working directory.

BUT - Py 3.3 at the command prompt uses my 3.3 working directory, and Py
2.7 ALSO uses the 3.3 working directory, which is not what I want,
obviously. Those are two different sets of scripts that won't always play
together.

Is there a way to set up each different interpreter, either Py 3.3 or Py
2.2, to automatically change to a particular working directory when you
call it - with a command line switch for instance? I can os.chdir after it
starts, of course, but that's a drag and I'll forget to do it at some
point. If I can do that from the call to Python I can make a batch file for
each one, with two different names - and easy typing ones like Py27 and
Py33 ;')

I see one possible candidate in python --help
-c cmd : program passed in as string (terminates option list)

But what does "program passed in as a string(terminates option list)" mean?
How do I stringify import os > os.chdir('my directory') ? That's unclear to
me.

Speaking of Py distributions I used ActiveState for various reasons, but I
looked at Enthought Canopy and was really annoyed. You can go over their
entire website and they don't tell you which Python version it's for - 2.7
and 3.3 being a bit different. It's almost like they hide it. ActiveState
makes it clear so I used them. I'm pretty sure Canopy is for 2.7 but I'm
not going to do a huge download on a slow connection when they don't tell
you.
