How to write hello world with web.py
Solution
import web
urls = ("/.*", "hello")
app = web.application(urls, globals())
class hello:
    def GET(self):
        return 'Hello, world!'
if __name__ == "__main__":
    app.run()
###Tip: Make url ending with or without ‘/’ going to the same class.
add the following to the beginning of urls.
'/(.*)/', 'redirect',
and have the following class to handle those urls.
class redirect:
    def GET(self, path):
        web.seeother('/' + path)
