Answer 1

You can make the URL entry as below to give you more flexibility when creating your url routing table

- url: .*
  script: main.app

Answer 2

The error is indicating that the url entry in your app.yaml is not valid. Try this

url: /udacityassignment2

And as Tim pointed, the mapping should be

app = webapp2.WSGIApplication([
    ('/udacityassignment2', MainHandler)
], debug=True)
