Hello SeaPIG,


I wonder if anyone knows how to address the following issue.  I looked in a
book and Googled for a while and couldn't find what I'm looking for.



I want to have a directory or set of directories that contain Python scripts
which I can execute from anywhere in my file system.  Right now, I'm
concerned with Windows XP, but I may want to do the same in Mac OSX and
Linux in the future.  Essentially, I want to by able to type:



currentDir>>>python script.py arg1 arg2



Where arg1 and arg2 might be files in the current directory that act as
inputs to the script and script.py is a script that resides in another
directory.



Here are some ideas I considered:



   - Setting the PYTHONPATH variable to include a directory where script.py
   is stored.  This did not work.  It seems to only work for importing
   modules once the Python interpreter is already invoked.
   - I read online and in a book that you can set "#!/usr/bin/python" as the
   first line in a script, assuming that this is the full path to the
   interpreter, put the script in /usr/bin or any other directory to which PATH
   points, and run the script using ">>>script.py".  I read that this is
   only an option in Unix, however, and it doesn't allow me to specify the
   version of Python I want to use as would be possible if I prefixed the
   script submission command with ">>>python26 script.py".  This also
   precludes me from using ">>>run script.py" from within Ipython.



Does anyone know how to handle this?  I noticed that I run the same script
by copying the script into the directories in which I want to run it, but
when I make revisions to the script, I have different versions sitting in
different directories, which is becoming very difficult to manage.



Thanks,

James
