Python developers are in high demand, and job adverts for this role have flooded the job boards.

As experts in algorithms, they are highly skilled in this major programming language. The expertise of countless developers around the world has made Python an indispensable tool for artificial intelligence and big data.

Python is an open-source programming language. It owes its popularity to its ease of learning, its simplicity of use and its wide range of applications. Python is the main programming language used for scripting and automation (robotics, big data, web applications and services).

Artificial intelligence systems and machine learning have widely adopted it because it comes with numerous built-in libraries that save time

Overview and responsibilities of a Python developer

They are also known as Python developers, designers or programmers. Whether working on applications, web services, robotics or big data projects, Python developers carry out a range of tasks: analysis, creation, improvement and transformation.

They follow the specifications set out by the AI project manager, lead developer or technical director. They work alongside other developers and also with the data science team when their work involves big data.

The preliminary design phase is generally carried out with the R&D teams, involving the construction of an architecture and adherence to the specifications. During the development phase, they focus on design, testing and deployment.

When working on an existing tool, they are required to review its structure and carry out sector-specific or comprehensive technological overhauls. Once a project is launched, the Python developer ensures it is used correctly and manages any functional and technical issues. They may work on bespoke solutions or develop the industrial-scale implementation of machine learning or deep learning algorithms.

Spam detectors, facial recognition, chatbots, the creation of personal assistance robots
 There are countless applications built using Python.

Business implications

Every sector needs Python developers: research centres, finance, the legal sector, the automotive industry, aerospace, pharmaceuticals, supply chain, the arts, media


The music streaming platform Spotify, the Shazam app, and social media platforms such as Pinterest and Instagram are the work of Python programmers and developers.

They work on cutting-edge technological projects related to data and artificial intelligence: robots, self-driving cars, connected devices, chatbots
 And on topics such as computer vision, natural language processing, fraud detection, predictive analytics, and many others.

Ethical implications
Algorithmic neutrality, data protection, the number of tests required before launching a project, biased datasets


Python developers are confronted with ethical and legal issues during their projects.

Legal experts in artificial intelligence or ethics officers provide solid support in ensuring that technological advances are aligned with respect for human rights.

aivancity’s programmes incorporate all aspects of artificial intelligence and its challenges – whether technical, technological, commercial, ethical or legal – into their curriculum. These are comprehensive, blended learning programmes that enable future engineers to acquire the highest level of knowledge and a broad range of expertise.
Key skills
Proficiency in Python is, of course, the core skill for a Python developer. Knowledge of other programming languages (JavaScript or Java). , databases (SQL, NoSQL), big data platforms (Hadoop, Spark), statistical analysis tools (R, Scala), and the ability to use software libraries (Pandas, Django, PyQt) are all valuable assets.

When discussing the qualities of a developer, patience always comes top of the list, and rightly so. Researching, testing, troubleshooting bugs and starting again make up a large part of their work. It also requires tenacity, rigour and curiosity.

Good communication skills are valued, as development is both an individual and a team-based endeavour.

As for teaching skills, these enable developers to interact and exchange ideas with colleagues who lack a basic understanding of programming. Keeping up to date with the latest developments and continuous training are essential requirements of the role.

Trends and factors driving change
Whether working in a digital agency, as a freelancer or within a company, Python developers work in a variety of roles. The next step in their career path is often a role as a project manager or lead developer, where they in turn manage teams.

Python developers are at work transforming our lives and practices. Their lines of code drive innovation.
