Getting Started with Django: A Web Framework for Understanding Python Programming

Getting Started Guide to Django: Understanding the Web Framework of Python Programming

Python is a programming language that has become increasingly popular in recent years. This language is very suitable for rapid development of Web applications. Django is one of the web frameworks of the Python programming language. It provides a fast, reusable and scalable way to build web applications. Django is a perfect implementation of the MTV (Model-View-Template) development pattern, which can develop content compatible with various web applications in a faster time.

Understand the Web framework of the Python programming language

Django is an open source Python programming language Web framework, invented and maintained by Noah Kalyi and his colleagues in 2003. It was designed from the ground up to quickly develop web applications, providing scalability and flexibility with minimal code. Django also provides a large number of out-of-the-box features, such as security management, site maps, management interfaces, RSS feeds, etc., which can help developers focus on the implementation of business logic.

Django is a framework for web application development. It extracts common patterns in web development to make development work easier and more efficient. Django is an MTV (model-view-template) style framework. In other words, the developer's work will go through the following three steps in sequence:

1. Model - defines the structure of the data, which can be stored in the database.
2. View - The logic of data processing and page rendering is here.
3. Templates - Templates that render data into HTML pages.

Advantages of Django

One of the advantages of Django is the speed of web application development. Django's out-of-the-box configuration and modular design mean you can write web applications faster and be easier to maintain. In addition, Django uses Python, a language that is easy to understand and learn, so you don't need a long time to become familiar with the entire project code and can quickly understand each part.

Django also provides a wealth of features so that you don’t have to reinvent the wheel when developing web applications. For example, Django's admin backend provides complete data management capabilities and is immediately available during development. In most other frameworks, you need to write these functions yourself.

Django's security is also very high. During the development process, Django will perform various security checks to ensure that your web application can resist various attacks. For example, Django ensures the security of web applications by preventing common attacks such as SQL injection and cross-site request forgery.

Use of Django

To use Django, you need to install the Python environment first. Since Django is written in Python language, Django can only be used normally if Python is installed. Next, you can install Django through the pip tool. Just enter the following command in the terminal:

pip install django

After the installation is complete, you can start creating your first Django application. You can use the following command to create a project:

django-admin startproject mysite

where mysite is the name of the project you wish to create. When you run this command, Django automatically creates a default project template for you.

Next you need to start the Django server. You can use the following command to start:

python manage.py runserver

Now, you can enter http://127.0.0.1:8000/ in the browser to view your Django application. This will display the default "Welcome to Django" page.

Conclusion

Django is one of the web frameworks of the Python programming language. It's fast to develop, safe, reliable, and ready to use right out of the box. Django uses Python, is easy to learn and understand, and excels in the field of web application development. By learning Django, you can develop high-quality web applications faster.
