What Does A Python Developer Do?


In this blog, we will explore why Python is a popular programming language, what Python developers do, and their career trajectory and future growth.

Have you ever seen the impeccable images of space that NASA captured with the James Webb Space Telescope (JWST)? If you haven’t, it is a sight to behold.

Although comprehending the vastness of the universe is nearly impossible, the technology JWST uses to capture remarkable images is more grounded than one might expect. 

Surprisingly, the general-purpose programming language Python played a significant part in enabling JWST to take and organize these images. If space is not a limit, imagine what Python can do here on Earth.

Artificial intelligence, machine learning, data analytics, data visualization – you can achieve all these by having a Python developer on your team! But the language doesn’t limit itself to these arenas. 

It has vast applications in game development, web development, app programming, web scraping, various quantitative and qualitative analyses, and graphic design.

Although there is sufficient proof to justify why Python programmers are the most coveted in the IT landscape, let’s dive deeper to reverse engineer how they reached this stature. 

Why is Python Popular?

With Python, the sky is the limit. It makes the life of developers drastically easier; thus, it’s the 2nd most-used programming language with a community of 15.7 million developers. 

Python’s popularity in web and software development stems from its ability to create intricate, multi-protocol applications while retaining a concise and readable syntax. Notably, numerous widely used applications have been developed using Python. 

Moreover, Python’s open-source community offers developers a wealth of reusable code, frameworks, and assistance. 

For instance, Django, a well-known Python framework, was created by experienced developers to aid others in accelerating their application development process and overcoming potential obstacles that could hinder their progress.

Pros of Python

  • Open-source community
  • Easy to learn
  • Increases speed and productivity in complex applications
  • Strong standard library
  • Portable and interactive (can be run on different platforms without changing the code)

Cons of Python

  • Slower runtime as compared to compile languages like C or C++
  • Slower execution as code in interpreted line-by-line
  • Higher memory usage
  • Offbeat choice for mobile development
  • Limited access to the database

Use Cases of Python

The versatility of this programming language makes it the preferred solution for many big names out there. Here is a list for your review:

  1. Google – Python finds applications in various aspects of Google, such as core search algorithms, APIs, and Google App Engine, illustrating the extensive dependence of the teams on this adaptable programming language.
  2. YouTube – According to OmniCore, it has 2.5 billion active users, 1 billion hours of video watched every day, and revenue of $29 billion in 2022. The language’s famed speed is put to use by developers to create features quickly. 

Whether viewing videos, controlling web templates, accessing canonical (duplicate) data, etc., it’s all Python behind the scenes.

  1. Facebook – Per the Lead, Python constituted 21 percent of the platform’s infrastructure codebase in 2020. Facebook has an extensive user base, which results in the usage of thousands of libraries and writing millions of lines of code.

Python manages Facebook’s hardware lifecycle, encompassing tasks like scheduling, automating maintenance, server imaging, and network switch setup. 

  1. Netflix – The responsibility of security, algorithms for recommendations, and proprietary content distribution networks falls on the shoulders of Python developers. The language is used extensively for content recommendations, personalized artwork, and even marketing. The Python libraries are used for analyzing large data sets.
  2. Spotify –  At Spotify,  80% of the back-end services are written and maintained by Python developers for extracting user data and analyzing it to recommend relevant songs and playlists.

The company also heavily utilizes Python async frameworks to assist services that experience input/output (IO) bottlenecks.

Therefore, hiring Python developers for your business is bound to bring good results.

What are Python Developers?

They are dedicated developers who design, code, and deploy projects in Python. Moreover, ensuring that these projects function as intended through debugging also falls into the scope of their responsibility.

That said, their home base is usually server-side (backend).

A Python Developer could be tasked with various responsibilities in a typical workday, such as developing applications for the employer, designing the code framework, building necessary tools, creating websites and integrated systems, and launching new services.

Working as a Python coder also entails working on cross-team projects. 

It is normal to see Python programmers working with data collection and analytics teams to answer business questions and derive insights.

In addition to this, some specific roles and responsibilities for every Python programmer vary according to the industry they are working in.

Why are Python Developers in Demand?

Python is in great demand in the corporate world due to its versatility in development and data analysis tasks. As a result, job seekers often prioritize learning and mastering Python as a top skill. 

According to Statista, recruiters worldwide ranked Python as the third most sought-after programming language in 2022, and 40% of employers are actively seeking candidates with Python proficiency.
