Question

import webapp2

class MainPage(webapp2.RequestHandler):
    def get(self):
           


        

Answer 1

i dont use the GAE launcher but im pretty sure that if you start your app with the launcher it puts some packages into your pythonpath thats why you can import it in your app.
i bet you cant import something from the gooogle.appengine.ext or other gae libs from your python prompt but you can in your app.
