Python full stack developer course in Chennai

In full-stack development, Python is mainly used on the back-end to build the logic and server-side operations. It helps create APIs, connect to databases, handle user data, and manage the application’s overall workflow. Frameworks like Django and Flask make it easier to build powerful back-end systems quickly.

In Python, I usually use an ORM like Django’s ORM or SQLAlchemy to interact with databases. For example, I can define tables as Python classes and perform actions like create, read, update, or delete using simple Python commands instead of writing raw SQL queries.

I utilize HTML to create the structure, CSS to apply styles, and JavaScript to handle user interactions. For more dynamic interfaces, I work with libraries like React or frameworks like Vue.js. These tools connect with the Python back-end through APIs or server-rendered templates like Django Templates or Jinja2 (in Flask).

A REST API allows the front-end and back-end to exchange data. In Python, I can create a REST API using Flask or Django REST Framework. The API receives requests, performs logic (like reading from a database), and sends back data in formats like JSON.

Django provides a built-in authentication system to handle user login, logout, and password management. In Flask, I use extensions like Flask-Login and secure password handling methods like hashing. I also use sessions or tokens to keep users logged in securely.

Templates are HTML files that display dynamic content from the back-end. Django templates are built with the Django Template Language, which allows dynamic content rendering. In Flask, templates use Jinja2. These templates allow us to write HTML with placeholders that get filled with data when the page loads.

To make the app responsive, I use CSS frameworks like Bootstrap or Tailwind CSS on the front-end. I ensure the layout adapts smoothly across various screen sizes. I also ensure fast loading, smooth navigation, and easy-to-use forms for a better user experience.

I write unit tests for the back-end using Python’s unittest or pytest. For front-end testing, I manually test forms, buttons, and navigation or use tools like Selenium. I also test the connection between the front-end and back-end using tools like Postman.

Yes. I built a blog application where users can sign up, write articles, and comment. I built the back-end with Django, integrated it with a PostgreSQL database, and utilized Django Templates for the front-end. The site had login/logout, form validation, and an admin panel to manage content.
