Django is an open-source web framework that is written in Python. It provides a high-level framework to build web applications quickly and with clean, pragmatic design.
Django leverages Python’s simplicity, readability, and extensive ecosystem to provide a set of tools for building and maintaining robust web applications.
2. Django Uses Python for Backend Logic
Django applications are built using Python for all the server-side logic. This includes things like database queries, business logic, views, and controllers.
The primary language for developing applications within Django is Python. You write models, views, forms, and other backend components in Python.
3. Django Follows the MVC Pattern (Model-View-Controller)
Though Django follows the Model-View-Template (MVT) pattern, it is conceptually similar to the Model-View-Controller (MVC) pattern used in many web frameworks.
Model: Python classes (typically using Django's ORM) define the database schema.
View: In Django, views are Python functions or classes that take HTTP requests and return HTTP responses, often with rendered templates.
Template: Django uses HTML templates, and logic to dynamically generate HTML is handled in the Python view logic.
4. Integration with Python Libraries
Django leverages Python's extensive standard library and external libraries. For example, you can use Python libraries for data processing, machine learning (e.g., NumPy, Pandas), or interacting with APIs (e.g., requests).
Many Python tools, such as those for authentication, session management, and handling asynchronous tasks, are easily integrated into Django applications.
5. Python as the Command-Line Interface for Django
Django comes with a built-in command-line tool called manage.py. This tool is written in Python and allows developers to perform various tasks like:
Running a development server
Migrating databases
Creating models or admin interfaces
Running tests
All of these operations are managed by Python scripts.
6. Django's Pythonic Nature
One of Django's core philosophies is to make the web development process as Pythonic as possible. This means it strives to make things as simple, intuitive, and readable as they would be in Python, adhering to the Zen of Python.
This results in Django being accessible to Python developers and allowing them to rapidly develop web applications using Python's elegant syntax.
7. Python Environment for Django
Django runs in a Python environment. To set up a Django project, you typically use tools like pip (Python’s package manager) to install Django and other dependencies in a virtual environment.
It's common practice to work in a virtualenv to keep project dependencies isolated.
Summary:
Django is a Python web framework that allows developers to build web applications using Python.
It leverages Python's features, such as readability, simplicity, and a strong ecosystem of libraries, to create robust web applications.
All the core logic (views, models, and forms) is written in Python, and Django's structure and components are designed to be intuitive for Python developers.
