import web ImportError: No module named web

[harsha]

I am new with GAE. Started with installing python 2.7.1 and GoogleAppEngine-1.4.2 on Windows 7.

And I am using SQLite 3. Then I followed instructions on Web.py site to install web module. python setup.py install

When I import web module on python console it works as expected 

$python

Python 2.7.1 (r271:86832, Nov 27 2010, 18:30:46) [MSC v.1500 32 bit (Intel)] on win32

Type "help", "copyright", "credits" or "license" for more information.

>>> import web

>>>

I created a sample application using web.py framework. Here is my code.py

==============================================================

import os

import web

from web import form

os.path.join(os.path.dirname(__file__), 'templates/')

render = web.template.render('templates/')

db = web.database(dbn='sqlite', db='testdb')

urls = (

'/', 'index',

'/todo(/?|/edit/?|/delete/?)(\d*)', 'todo'

)

app = web.application(urls, globals())

class index:

def GET(self):

return render.index()

class todo:

def GET(self,mode,args):

if args:

items = db.select('todo',where='id={0}'.format(args))

item = items[0]

todoform = form.Form( 

form.Textbox("id", value=item.id), 

form.Textarea("title", form.notnull, value=item.title),

form.Textbox("created", value=item.created),

form.Checkbox('done', checked=(item.done!='f'))) 

return render.todo_item(todoform(),mode)

todos = db.select('todo')

return render.todo(todos)

def POST(self,mode,args):

i = web.input()

if args:

if mode == "/delete/":

n = db.delete('todo', where='id={0}'.format(args))

raise web.seeother('/todo')

if mode == "/edit/":

taskdone = "t" if (i.has_key('done')) else "f"

n = db.update('todo', where='id={0}'.format(args), title=i.title, done=taskdone )

raise web.seeother('/todo')

else:

n = db.insert('todo', title=i.title)

raise web.seeother('/todo')

if __name__ == "__main__": app.run()

==============================================================

And this code works as expected when I start server from command line 

==============================================================

Then to deploy I added app.yaml and index.yaml files in same folder as code.py

When I run dev_appserver.py  I get     import web ImportError: No module named web

I copied entire web folder of web.py-0.34 to code.py folder and thus
solved import web issue.

But now I am having issue with sqlite3. How to solve sqlite issue?

Please help

You can't use sqlite database on app engine. You need to use google
datastore instead.
