Data science is a very complex field that requires the insights of professionals from many different disciplines. One of the fields of professionals that are so important for data science projects are Python developers.

What is the Python programming language? Why is it so important in the data science profession?

What Is Python?

Python is a powerful programming language that is widely used in many different industries today. There are 8.2 million Python developers in the world today! That figure is growing as more teams need them to work on projects involving data analytics, AI and similar technologies.

Python developers are in high demand, and as a recruiter, knowing the roles and responsibilities of a Python developer is essential to finding the best candidates for your open positions. You will have a better understanding of the importance of using Python to create data science applications, which will make it easier to hire the right candidates.


In this blog post, we will outline the key roles and responsibilities of a Python developer and provide tips for recruiting them. So, if you’re looking to add a Python developer to your team, read on!

Python is a versatile scripting language that was first released in 1991. Python is used in many different fields today, including web development, software development, scientific computing, artificial intelligence, and more. Python is known for being easy to read and write, as well as being very reliable. Due to these benefits, it is an ideal programming language for the data science profession.

What Does a Python Developer Do?

A Python developer is responsible for writing code in the Python programming language. They may work on web applications, desktop applications, or back-end systems. Python developers typically work in a team of developers, and their job may also include working with databases, debugging code, and providing support to end users.

Python Developer Roles and Responsibilities

Let not waste any more of your time and get straight to some of the most common Python developer work roles and responsibilities.


Common roles and responsibilities of a Python developer include:

  1. Developing back-end components for data science applications
  2. Connecting applications with third-party web services
  3. Creating scalable, testable, and efficient code which is necessary for handling programs that compile large datasets
  4. Identifying and fixing bugs and performance issues
  5. Writing documentation
  6. Coordinating with other developers and data scientists

You can probably understand how these functions make Python the perfect programming language for creating AI and big data applications.

What are some of the requirements a Python developer working on big data applications should have? Here are the most common ones:

  1. Strong experience with Python programming and an understanding of big data frameworks it will work with
  2. Experience with popular Python frameworks (Django, Flask, etc.)
  3. Experience with object-oriented programming
  4. Strong problem-solving skills
  5. Excellent communication and collaboration skills
