The code below works (in linux), but I'm wondering if there is a
better/easier/cleaner way? It works on directory trees that don't
have a lot of "."s in them or other special characters. I haven't
implemented a good handler for that yet, so if you run this in your
system, choose/make a simple directory structure to use as your root
for os.walk(). Also, you must start from the top most directory
level, like /test. /tmp/test as a root will not work (yet). :)
I wanted to know if I could use os.walk() to construct an object based
off of a directory tree. So, the following path: "/test/home/user"
would get converted into "test.home.user" and I could then work with
it that way in my python program, attaching attributes to those
"directories" that I could use to keep track of things. This was more
of an exercise in learning than anything, I wanted to see if I could
do it. I've never used "type()" before to create new objects, so
really that was the point. Can I do this an easier way though?
