Also, note that you don't use "print" in web2py -- printing prints to the console and has no effect on the HTML returned by the server to the browser. In web2py, a controller action returns a dictionary of data, and the view then uses that data in constructing the HTML. Controllers do not directly write into the view -- that is why controllers and views are separate layers -- they each have their own roles.
