why we use if __name__== '__main__'

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: Proctor was kind and helpful. Sir was asking lots of theory questions. So, prepare well. AND have the all logic of the routes clear because you have to explain the logic without opening the app.py or any route. Sir will help you if u find any difficulties while changing the code. Didn't have any of the question from sir in this sheet for this term But I have preferred his PYQs from this sheet(only 2 entries where there).So, Hope this will help!!! All the very best!!!
