From what I can understand, it is just the problem with the Python Installation because the app works fine when deployed.

I have Installed Python 2.5.2.

What exactly is going on?

    I assume from the logs the the reason is that you are trying to run app engine with python25.

    Options 1: Edit your app.yaml and put python25 at your runtime. The rest you can leave it as you have it setup 

    application: bismillah
version: 1
runtime: python25
api_version: 1

    Option 2: Install python 2.6 or python 2.7 and either make it your system default either just use it only for google app engine

    Python 2.7

    Google App Engine Application setup
