This is a pretty common problem when working with regular expression (which usually contain many backslashes) - that's where I saw this syntax for the first time (e.g. http://docs.python.org/lib/match-objects.html).

MySQL distributions (at least on Linux systems) are usually split into server and client packages. If you install the mysql-client package on the server, you'll have all you need (libs and stuff) to access a remote server - without the mysql server itself. Not sure about the windows, although I would guess that the installer let's you choose which parts to install (client libs/tools, server or both). -- http://mail.python.org/mailman/listinfo/python-list
