What do Python developers do?

Python developers are in charge of creating software using the Python programming language. They are generally focused on the back end of websites or applications, i.e., the architecture, unlike front-end developers, who manage the visual aspects. 

A Python developer’s role includes:

  • Designing programs to function as clients need them to.
  • Using critical thinking and creativity as you code.
  • Identifying and implementing optimal tools for building or enhancing powerful, modular applications.
  • Using tests to monitor applications and ensure the highest quality service.
  • Providing technical and functional documentation of an application for clients and colleagues.
  • Staying up-to-date with quickly evolving technologies - developers are lifelong learners!

Why complete this training?

The number of software developer jobs is projected to grow by over 20% from 2018 to 2028 due to unprecedented growth in the tech sector (source: US BLS). In particular, Python programming is one of the most in-demand skills in the current job market.

Here at OpenClassrooms, our mission is to make education accessible. OpenClassrooms is a global online education-to-employment platform, designed to teach the skills needed for the most in-demand jobs. We pinpoint the key skills needed to succeed in the job market and create world-class online programs to train our students on those skills. 

That’s why we've developed this 12-month bachelor-level diploma in Python development, which you can complete entirely online with the help of a dedicated mentor.

This training was designed and created by our learning design team in collaboration with a committee of Python experts. It consists of 13 projects of increasing complexity. Each project is based on a concrete scenario from the professional world and will allow you to acquire specific skills. Your mission: find solutions, produce professional deliverables, and present them convincingly to a mentor. You will be able to directly apply your experience to the workplace.

What you will learn

By completing this path, you will develop the following Python developer competencies:

  • Set up your development environment using virtual environments and PyCharm.
  • Create web applications using the Django and Django REST frameworks.
  • Develop a secure PostgreSQL database.
  • Enhance applications with testing, debugging, and refactoring.
  • Use technologies like GitHub, Postman, HTML, CSS, JavaScript, and CircleCI.

...and much more!

At the end of this training, you will have a portfolio of professional projects and earn your European diploma for software development.
