Ok... i'm a zope user (not a good one), and long time perl user.
Each time i get a little 'utility' type project, I think "A ha..  I'll
use Python this time" - then the time gets low, i never get around to
it, and say  "heck, i'll just do it in Perl".....

So this morning I said no - wanna get the first one under my belt !

realized the machine i'm using doesnt have Python - so loading it now.

.... here's my goal.....

I need to copy 80,000 files from one directory and put them in one of 20
other directories.  I'm into chaper 12&13 in the pyton book, and am sure
I can get the looping structure over the directory listing....

But to progam the logic to decide where the files go, I need substring
parsing of the file names (think thats easy) PLUS something like a CASE
statement.  I don't see the CASE statement anywhere.

So will i have to use a bunch of cludgy if/then statements, or is there
something more elequent...

  if subval > "0001"  and subval < "0010" :
     <filecopyingsteps>
 elif subval > "0009"  and subval < "0020" :
     <filecopyingsteps>
........

Thanks
(python 2.2.1 is installed...whoo hoo!)
