WSGI
WSGI (Web Server Gateway Interface) is a Python specification that defines a standard interface between web servers and Python web applications or frameworks. It allows web servers to communicate with Python applications, enabling the deployment of Python web apps across different server environments. WSGI promotes interoperability by separating the server from the application logic.
Developers should learn WSGI when building or deploying Python web applications, as it is the standard for connecting Python code to web servers like Gunicorn or uWSGI. It is essential for deploying frameworks such as Django or Flask in production environments, ensuring compatibility and scalability. Understanding WSGI helps in debugging, optimizing performance, and integrating with various server technologies.
