ImportError: No module named *

Question

I want to create a web site on GAE.

I have an error importing module. Is something wrong in my code and structure?

ImportError: No module named appsite

　　　|-public.py

app.yaml

handlers:- url: .*
script: appsite.public.app  
libraries:  
- name: webapp2  
version: "2.5.2"

public.py

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

Answer 1

You must add __init__.py file under appsite directory.

The __init__.py files are required to make Python treat the directories as containing packages;
