3. wsgi.py
(Web Server Gateway Interface):
- This file is used for deploying Django applications on traditional web servers like Apache or Nginx. It acts as an entry point for web servers to interact with Django.

.
4. asgi.py
(Asynchronous Server Gateway Interface):
- This file is used for deploying Django applications that utilize asynchronous features and technologies, such as Django Channels. It's an entry point for ASGI servers like Daphne or Uvicorn.
