Python has grown into one of the most preferred languages for web development, not just because of its readable syntax but also due to its robust frameworks. If you're planning to build a web application, Python offers a well-organised development flow, supported by powerful tools like Flask and Django.
Starting a web application project with Python begins with understanding the business logic and choosing the right framework. Flask is known for its simplicity and is often used in small to medium projects. On the other hand, Django comes with many built-in features and suits complex applications that need user authentication, admin panels, and structured routing.
Once the framework is selected, the next step is setting up the development environment. Python virtual environments help keep dependencies isolated, making it easier to manage project-specific packages. This is followed by creating templates, routes, and connecting your application to a database.
A strong backend structure is the backbone of any functional web application. Python supports integrations with databases like MySQL, PostgreSQL, and MongoDB. With the help of Object Relational Mappers (ORM) like SQLAlchemy or Django ORM, developers can work with databases without writing raw SQL queries.
Security is also a key part of web development. Python’s frameworks provide built-in methods to manage sessions, validate input data, and avoid vulnerabilities such as CSRF, XSS, and SQL injections. Adding user authentication and authorisation is straightforward with Django’s built-in user model or Flask extensions.
Testing is another phase that shouldn’t be overlooked. Python supports unit testing using tools like Pytest or unittest. Writing tests helps confirm that features work as intended and reduces the chances of unexpected issues after deployment.
