RESTful API

RESTful API (Application Programming Interface) is a standard web protocol that is widely used for web development. APIs are the foundation for building complex web applications that require a standardized way of exchanging information.

Flask comes with a built-in support for

RESTful APIs, making Flask one of the most popular web frameworks.

Advanced Techniques and Tools

In addition to the basic web development concepts, advanced web development with Python incorporates skills such as database programming and continuous integration/continuous delivery (CI/CD). Developers use HTML and CSS to design visually appealing web pages and apps.

They also use specialized tools such as Behavior-Driven Development (BDD) to ensure that their web apps function as expected.

Web Scraping and Crawling

Web Scraping and Crawling refer to the techniques used to extract data from websites for various purposes, from research to data analysis. Python’s versatility and extensibility make it a popular language for web scraping and crawling applications.

Django

Django is a high-level Python web framework that is used to build scalable, maintainable, and secure web applications. It provides an all-in-one solution for web development and is used by leading technology companies such as BBC, Mozilla, and Instagram.

Conclusion

To conclude, Python is a powerful programming language that can be used for various tasks, from scripting to web and mobile development. Python’s popularity and ease of use make it beneficial for beginners and professionals in the tech industry.

If you are looking to get started in programming or want to expand your knowledge, Python is an excellent choice to consider. Advanced Web Development with

Django Development

Software Craftsmanship

Software craftsmanship is a set of principles and practices that focus on creating high-quality software.

In

Django, this means building maintainable code, using the model-view-controller (MVC) architecture, and writing efficient tests. The goal is to create clean, reusable code that can withstand changes and updates.

Test Driven Development

Test Driven Development (TDD) is a software development methodology that values writing tests before code. This way of working ensures that the code produced meets the desired requirements in a systematic way.

It also automatically writes the tests for future reference.

Git Branching

Git branching is a technique used in software development to manage code changes. It allows developers to work on multiple versions of code at once, making the development process more efficient.

By using Git branching, developers can work on new features without interfering with the main codebase.

Upgrade Management

Upgrades are an essential part of software development. In

Django, it is vital to manage upgrades to ensure that users can use the latest features without any issues.

Django provides built-in tools for managing upgrades, making it easy to keep up with the latest version of the framework.

Graceful Degradation

Graceful degradation is a software engineering principle that involves building applications that function even when certain components are unavailable.

Django provides mechanisms for handling errors and missing resources so that the site functions even when these resources are not present.

Membership Site

A membership site is a web application that restricts access to certain areas based on user authentication.

Django provides built-in mechanisms for managing user authentication, making it easy to build membership sites.

Bootstrap 3

Bootstrap is a CSS front-end framework used to create responsive and mobile-first web applications.

Django provides integration with

Bootstrap 3, allowing developers to create visually appealing and responsive web applications more efficiently.

REST

REST (Representational State Transfer) is a set of architectural principles for building web applications. In

Django,

REST is implemented using the

Django

REST framework, which provides a set of tools for building

RESTful applications.

The

Django

REST framework provides authentication and serialization capabilities, making it easy to build
