Python for web development refers to the use of the Python programming language for building websites and web applications. Python is a high-level, interpreted programming language that is widely used for web development because of its ease of use, flexibility, and readability.
Web Frameworks in Python
Web frameworks are pre-built libraries or modules that simplify the process of web development. Here are two popular Python web frameworks for building dynamic websites:
- Flask: Flask is a lightweight web framework that is easy to set up and use. Flask allows you to build web applications quickly and efficiently. Flask is best suited for small and medium-sized web applications. It is a micro-framework that gives developers complete control over the web application's architecture. Flask has a small footprint and is highly extensible.
- Django: Django is a popular web framework that is used to build large, complex web applications. Django is an all-in-one solution that provides everything you need to build a web application, including authentication, database management, and more. Django is a full-stack web framework that follows the Model-View-Controller (MVC) architecture pattern. Django is highly scalable and can handle large amounts of traffic.
Building Dynamic Websites with Python
Dynamic websites are websites that display content that changes frequently. Dynamic websites are built using server-side programming languages such as Python. Python can be used to build dynamic websites by using web frameworks such as Flask or Django. Here are some of the key technologies used in building dynamic websites with Python:
- HTML: HTML is the standard markup language used for building web pages. HTML is used to structure content on a web page and define its layout. Python web frameworks like Flask and Django use HTML templates to generate dynamic web pages.
- CSS: CSS is used to style HTML content. CSS is used to define the layout and appearance of a web page. Python web frameworks like Flask and Django allow developers to use CSS to style web pages.
- Database: A database is used to store and manage data for a web application. Python web frameworks like Flask and Django support a variety of databases, including MySQL, PostgreSQL, and SQLite.
- SQL: SQL stands for Structured Query Language. SQL is used to manage and manipulate data stored in a database. Python web frameworks like Flask and Django provide support for using SQL to manage data in a database.
Once the web application is developed, it needs to be deployed to a server so that it can be accessed by users. There are several deployment options available for Python web applications, including:
- AWS: Amazon Web Services (AWS) is a cloud computing platform that provides a wide range of services for hosting and deploying web applications. AWS provides scalable and reliable infrastructure for hosting web applications. Python web frameworks like Flask and Django can be deployed on AWS.
