MacPorts does not overwrite software installed by the system; it confines its activities, for the most part, to the /opt/local directory. So your existing Snow Leopard installation of Python 2.5 has not been corrupted or touched in any way by MacPorts.

There is no MacPorts password; this is asking for your Mac user account password. If you do not have one, then you cannot use the sudo command  and consequently cannot uninstall MacPorts (nor, I imagine, install anything with it, for that matter). I just learned this a very short while ago in troubleshooting with another user. You must assign a password to your user account in System Preferences > Accounts. Then you can proceed to either use MacPorts or uninstall it.
