asked about the if name=="_main_", which i somewhat told

Times asked 1

Official solution

Simple== value. is identity same object. Speed micro. None: is None.
Difference is and ==. Performance negligible vs correctness.
Pehle 1-line definition, phir related MAD2 layer (Vue SFC / Flask route / models.py / tasks.py / Redis).
4-line formula: input kahan se aaya, auth/validation kaunsa, DB ya cache ya Celery, kya return.
Related mix mat karo — cache ≠ Celery, authentication ≠ authorization, v-if ≠ v-show, Beat ≠ Worker. Follow-up ke liye ek difference ready rakho.
Project example: if user is None. Don't is for strings.

Asked what if __name__ == "__main__": means in app.py.

Times asked 1
Official solution

Simple
```
if __name__=='__main__' only when file run directly. Import pe nahi — app.run yahi. Remove import pe server start ho sakta.
```
Celery/tests import app without serving. Why used.
Flask Python micro web framework. Route decorator URL → function. MAD2 mein JSON API: request.get_json(), jsonify, JWT.
WSGI: server (Werkzeug) app ko call. if __name__ == '__main__' sirf direct run. Factory create_app() test/celery ke liye.
Blueprint/resources folders. @app.route vs MethodView. Debug=True viva local, prod nahi. CORS alag port Vue ke liye.
Project example: app.py bottom.

Advice: Very chill proctor. Be confident while answering. He helps if you get stuck anywhere. Be ready to explain basic project setup, venv, and key code lines from app.py and models.py. Be prepared for small live changes in the UI during the viva.
