Python Flask Basics
Python Flask is a lightweight and popular web framework used for developing web applications in Python. It is called a micro-framework because it provides only the essential tools needed to build web applications, while allowing developers to add extra features through extensions. Flask is simple, flexible, and easy to learn, making it suitable for beginners and professionals.Flask was developed by Armin Ronacher and is based on the WSGI toolkit and Jinja2 template engine. It helps developers create web applications, APIs, and dynamic websites with minimal code. Flask follows a modular approach, giving developers control over components like databases, authentication, and routing.Flask supports handling HTTP methods such as GET and POST, which are used in forms and data submission. It also supports templates using Jinja2, allowing HTML pages to display dynamic content.
Another important concept is request handling. Flask can process user input from forms, query parameters, and APIs. Developers can also use Flask with databases like MySQL or SQLite to store and retrieve data.
Flask extensions add more features, such as Flask-SQL Alchemy for databases and Flask-Login for user authentication.
Advantages of Flask include simplicity, flexibility, minimal setup, and scalability. It is widely used for web development, REST APIs, and prototype applications.
In conclusion, Python Flask is a simple yet powerful framework for building web applications. Its basic features such as routing, templates, request handling, and extensions make it an excellent starting point for learning web development. One of the basic concepts in Flask is routing. A route connects a URL to a Python function. For example, when a user visits the home page, Flask calls a function and returns a response. #snsinstitutions #snsdesignthinkers #designthinking
