- Handling HTTP requests and responses.

- Database interactions via libraries like SQLAlchemy or Django's ORM (Object-Relational Mapping).

- Building APIs using frameworks like Django REST Framework or Flask-Restful.

The simplicity of Python allows backend developers to focus on business logic rather than the intricacies of the language, accelerating development cycles.

## 5. Full-Stack Development with Python

Python is also widely used in full-stack development, where a developer handles both the frontend and backend. While Python is predominantly known for its backend capabilities, tools like PyScript allow developers to use Python in frontend development as well.

### a. Integration with Frontend Technologies

Python can easily integrate with frontend technologies like HTML, CSS, and JavaScript through templating engines such as Jinja2 (used in Flask). These templating engines allow Python to dynamically generate HTML content based on server-side data.

### b. Python Frameworks for Full-Stack Development

In a full-stack environment, Python developers often use Django due to its "all-in-one" nature, which includes both backend and frontend components like form handling and templating engines.

## 6. Advantages of Python in Web Development

The growing adoption of Python for web development can be attributed to its multiple advantages, including:

- Rapid Development: Python’s clear syntax and powerful frameworks enable faster project development.
