[Tutor] How to verify all things are equal to one another

[Tutor] Any easy way to invoke the default browser on a specified URL?

Is there any way, from within Python, to cause the default browser (Firefox, in my case) to be invoked with a specific URL? I'd like to do something like (totally made-up name and syntax): OpenBrowser("http://www.google.com/";) and have a new browser window opened up pointing to Google. (Okay,
