If you don't have to worry about spaces in your strings, I'd just use split(). If you DO need to worry about spaces, it'd be trivial to write your own parser that stepped through the string a single character at a time. The shlex module does this, but might not work for you. I don't know how it would handle an IP address. -- https://mail.python.org/mailman/listinfo/python-list
