Are you sure the filename is correct?  As I understand it, Window's
filesystems are case insensitive, so 'textfilename.txt' would also
work for files named 'TextFileName.txt', or 'textfilename.TXT', etc.
I believe the Mac's filesystem is case sensitive, so all of those
names would be different files, and could in fact all reside in the
same directory together.

 Hi,
 
 If one does this...
 
 import sys
 sys.path.append(C:\\panda\direct)
 
 Is the change to python search path only temporary?
 Thanks.

As we quibblers like to say, That depends on the meaning of the
word temporary.

Modifications to sys.path (insert or append) last until the end of
the execution of your program.

Although there are times when modifying sys.path at run-time is
necessary, there is usually a better way.  Usually you will want
to add a path to the environment variable PYTHONPATH.  How you do
that depends on your platform (Linux, MS Windows, ...).

Yes, it only changes the search path within that program. The system-wide
default search path is not changed.

 When one installs a program (such as Panda or Livewires) into python
 sitepackage folder is the python search path automnatically updated to
 search the newly installed folders and files?

Generally speaking, yes. The Python package (to use the proper name) either
needs to have a files '__init__.py' in its package directory

(see http://pytut.infogami.com/node8.html, section Packages)

or the name of its package directory needs to be added to a .pth file

(see http://docs.python.org/lib/module-site.html)
