"Syntax error: sentence seems to be a question, but is missing a question mark." To answer your question, PYTHONPATH is an environment variable. You set it in your shell. For example, I use the bash shell under Linux, and in my .bashrc file I have this line: export PYTHONPATH=/home/steve/python/ Every time I log in, the shell sets the environment variable to the pathname /home/steve/python/, and then when Python runs, it appends that path to sys.path. I don't have to modify any Python source code. > Value stores in the system var sys.path, but the > first item of this list, path[0], is the directory containing the script > that was used to invoke the Python interpreter.

However, trying to guess what you want, PYTHONPATH doesn't *replace* sys.path, it appends to the end of it. This is usually the right thing to do. However, sys.path is an ordinary list. If you want to modify it, you can do so: import sys sys.path[0] = '/some/other/path' -- Steven -- http://mail.python.org/mailman/listinfo/python-list
