Advantages of Python Flask Over Other Framework

1. Python Flask is a lightweight framework with numerous extensions that can be picked based on the developer’s requirements.
2. Flask makes routing simple by mapping URLs to Python functions, Flask facilitates relatively simple URL management. This implies that Flask determines which Python code to call when someone visits your website at a URL.
3. Flask handles HTTP requests and responses and simplifies data exchange and formatting. This includes easy access to form data, file uploads, cookies, headers, and other HTTP-related metadata.
4. Flask internally handles requests and responses as Unicode, and it handles data conversion for you, making it easier to build apps for a global audience.
5. Flask uses Jinja2 as its template engine. This allows for the dynamic generation of HTML, XML, or other markup languages. We can create templates for the layout of our website and use placeholders for data that will be filled in when the page is requested.
