Python and Django

Among the most used backend frameworks, we find Django. Indeed, Django example websites look amazing. Django is one of the most popular Python frameworks that can help you cope with diverse tasks easily.

Django offers easier development while guaranteeing fewer lines of code to write; developers favor this framework as it saves time without losing quality.

The popularity of Python

Python is used by several giants present on the web. Amazon, Google, Facebook, Instagram, Netflix, Spotify, and Uber use Python in their backend part.

Python is known for making programming simpler and more intuitive. It quickly took a major place in many areas, such as automation, big data, machine learning, and software and applications development.

According to PYPL (PopularitY of Programming Language), Python has managed, since 2018, to rise to the top of the ranking of the most used programming languages. The programming language marks a strong and rapid progression that puts it ahead of Java and C#.

The advantages that led it to this popularity

Python is intended to be less restrictive for faster development. It was designed to optimize developer productivity through an easy-to-use code syntax.

In addition, the programming language works on any operating system, whether on Linux, Mac, Windows, or Raspberry Pi (Pi also means Python, the default language of the electronic card). This saves time since adapting your code to different systems is useless.

But also some disadvantages

Python is an interpreted programming language. This generates a longer loading time than with a native programming language. This is an element to consider if the speed of execution is an important point of the project.

In addition, Python’s syntactic writing can cause problems when executing the code. Indeed, if the code is poorly written or if you have made a mistake in indentation, the language can misinterpret the meaning of the variables and will therefore indicate an error.

The simplicity of programming language

Python is, therefore, simple to use but also to learn, especially if you are a beginner. Its syntax resembles spoken language, which facilitates its learning. No need to be careful and put braces, parentheses, or commas; a good indentation will be enough.

In addition, Python can understand for itself if what is written corresponds to a string, boolean, or array variable without specifying it.

Presentation of Django

As we have mentioned, Django is an open-source backend framework. It is developed under the Python programming language.

Created in 2003 by the local newspaper of Lawrence in the United States, the framework was sublicensed to BSD in 2005.

Today, Django is incredibly popular; it is one of the most used backend frameworks. Several social networks, such as Instagram or Pinterest, have chosen to use Django.

Getting started with the framework is quite simple. The documentation provided is rich and detailed, and the community is really active. In addition, developers have a forum set up by Django to promote mutual aid between the community.

All this allows developers who have never used the framework to take their first steps and start a project easily and independently. The only prerequisite: have basics in Python!

The guideline of the backend framework

The framework promises quick and easy development with little code to write. But less code does not mean less quality for the framework!

Indeed, a clean and quality code will be much more effective on several levels.

First of all, it makes it easier for developers to navigate between the lines. This quality also makes it possible to obtain better referencing from Google.

So, less code simply means that Django takes care of certain features to let developers customize the application according to requests. These features supported by Django can be database manipulation, URL routing, or vulnerability and security management.

Security

Django focuses on the security of applications developed under the framework. The goal is to help developers to avoid certain errors and flaws. Also, Django’s documentation gives many tips and best practices to avoid code flaws.

For example, Django protects the database from SQL injections.

Routing of URLs

Django encourages developers to configure clean URLs to develop web applications with quality code. To do this, you must create a Python module that will be used as a router in which we find the defined URL and the view used.

The MVC architecture

MVC stands for Controller View Model; it is a software architecture model Django uses. It is also widely used in other backend frameworks.

The model separates the three entities:

  • The controller is the intermediary between the model and the view. It verifies and manipulates the data. This is called business logic.
  • The model contains the data and returns it to the controller.
  • The view creates the graphical interface with the data sent by the controller to transmit it to the user.

Separating the three entities makes it easier to maintain the application because it is possible to change the view without touching the controller.

Similarly, the separation of entities promotes teamwork since a front-end developer will be able to work on the view at the same time as a backend developer will be able to work on the controller.

Conclusion

If you are still hesitating on technological solutions to use, contact professionals: everything will be discussed in the project discovery phase. All in all, Django is a mature framework that has acquired an active community. Designed for developers who do not have time, the framework helps maintain security and code quality. Very simple to handle, Python developers appreciate it for its versatility, allowing them to create all kinds of applications.
