Yes, and that path is a list, named 'path', in standard module 'sys'.

You can do, for example:
    import sys
    sys.path[0:0] = '/my/directory'
and on successive imports, "/my/directory" will be tried before other
directories on sys.path.

There are also more permanent ways to alter sys.path.  The handiest
one is to put a textfile, any name, extension .pth, in the Python
directory (the site-packages one, under Linux; just C:\Python22,
under Windows).  yourfile.pth can list any number of directories,
one per line; they will all be added to sys.path during startup
(by module site.py).  This makes your directories be appended AFTER
others in the path, though.  You can also define environment variable
PYTHONPATH, or, on Windows, hack the registry.
