There isn't a best way, really.

I'm partial to CherryPy. A minimal example would look like so:

-------------------------------
import cherrypy

class Root(object):
    page = "<html><head><title></title></head><body>%s</body></html>"
    @cherrypy.expose
    def enter_data(self, data):
        return self.page % ("You entered: " + data,)

    @cherrypy.expose
    def index(self):
        form = """
        <form id="aform" name="aform" action="enter_data" method="POST">
          <textarea name="data">Enter some stuff here</textarea>
          <input type="submit" value="Submit"/>
        </form>
        """
        return self.page % form

if __name__ == '__main__':
    cherrypy.quickstart(Root())

-----------------------------------

Note, I wouldn't actually recommend using string building like that for
returning pages unless your app is seriously trivial. I use Genshi for
templating, the tutorial that they have is very nice (and uses cherrypy).

There's a plethora of different ways to build web apps in python. In all
reality, you should probably try out a few and see what suits your tastes.
