Ques 3. What are the advantages of Django?

Most developers prefer Django due to its dominance in the market, as it shows high computational and statistical capabilities. The following are some of the advantages of Django:

  • Django follows Python’s ‘batteries included’ trait. Python is generally referred to as ‘batteries included’ because it has a unified standard library, helping developers use readymade packages to add features to a web project. 
  • Most of the packages in Python’s standard library are open-source. With these packages, you can even implement authentication, admin interfacing, session management, and other advanced functionalities. 
  • Python and Django are core technologies in IT giants, the Internet of Things (IoT), and blue chip companies. Therefore, learning it would help you establish a lucrative career. 

     

  • Security is yet another advantage of using the Django framework. Applications developed on Django are protected against SQL injection, clickjacking, XSS and CSRF attacks, etc.
  • The built-in template language of Django promotes the process of building applications. 
  • Django enables developers to create applications and configure frameworks on the go. Also, it offers support for external libraries and packages. Django focuses on explicit programming, allowing the developers to create applications that require frequent changes.
  • It helps in faster development and is thus used by most companies. If the configuration is correct, then you can use Django for optimizing web applications.
  • Django has a REST framework, a python library, that helps develop APIs for many applications. Using these APIs, you can add advanced functionalities to your applications.
  • Django comes with ML capabilities and libraries such as PyTorch, NumPy, etc.
