There are many things a Python developer can do. Create a new programming language or an app. Develop a new website or do quantitative analysis. They can do various programming tasks. 

Let’s explain what does a Python developer do exactly and even how to become a Python developer

What is Python?

Python is a programming language. It is also a general-purpose language. This means you can use it to develop a wide range of apps. But also means that is not specialized for any particular problem.

You can use it to build websites and apps. It is also a tool where you can automate tasks and conduct data analysis. The language is very simple and readable. Python offers a vast ecosystem of libraries and frameworks. This makes it a versatile choice for beginners and professional developers alike.

What is a Python developer?

A Python developer is someone who specializes in programming in Python. They can create software apps and websites. Their main job is to write, test, debug, and maintain Python code.

Python developers can build various digital solutions. They work on projects that involve the following:

  • Automating tasks; 
  • Developing web apps;
  • Analyzing data;
  • Creating artificial intelligence algorithms;
  • Use machine learning systems and much more.

As a Python developer, you will collaborate with different teams. You will also assist in answering questions and providing insight. Many popular companies use Python, such as:

  • Netflix
  • Facebook
  • Google
  • YouTube
  • Reddit 

Python developers are very popular. They are in high demand. This is because Python allows them to build scalable and cost-effective solutions. They also contribute to saving time and effort in the development process.

What does a Python developer do

A Python developer's job involves writing, testing, and maintaining computer programs using Python. They use software apps and tools. Then, they perform specific tasks or solve particular problems.

Python developers also document their work, providing clear instructions and guidelines. This is very useful for other developers or users. They stay updated with the latest Python libraries, frameworks, and technologies. Then, they use the to create the apps. Python developers can also do:

  • Database management
  • Deployment tasks. 

Their goal is to create efficient, reliable, and user-friendly software solutions.

Python developers collaborate with other team members. Including designers and engineers. This way, they ensure smooth integration and functionality of the software. They  also:

  • Debug and fix issues, 
  • Perform code reviews,
  • Optimize the performance of the apps.

With this background and skills, you can work in a remote job as a Python developer. You can also find a job in the company or even become a freelancer. 

What are the advantages of Python over others?

Python is simpler to learn than, for instance, JavaScript or C++. It is one of the simplest programming languages. Here are other advantages of Python.

1. Easy to learn

Python has an easy-to-understand syntax. It also has a big community. Such a community contributes to a variety of libraries and tools. This makes it a good choice for professional developers who need to pick up a new project rapidly. But also for beginners who are just starting to learn to code.

2. Very versatile language

Python is a very versatile language. You can use this language for various apps. But also for web development, data analysis, and scientific computing. This makes it an excellent choice for projects that need more tools and technologies. 

3. Python is an open-source language 

Open source means that anyone can use this programming language. It is publicly accessible. Anyone can modify it and edit it. They can also distribute the code as they wish. You can also use it for commercial use if you want. 

4. A great offer of libraries

Python has amazing libraries to offer. Programming libraries are valuable tools that can make the developer’s job easier. They provide pre-written, reusable code. That codes developer can use to make apps easily.

5. Easily portable and interactive

Some programming languages, like C++, need you to rewrite your code if you want to use it on different platforms. However, when using Python, you don’t need to do this.

You don’t need to change anything. Use the same code for different platforms, including: 

  • Windows
  • MacOS
  • Linux

Being interactive is very useful when there’s a problem, such as debugging. This way, you can view individual results and locate issues.

What tools do Python developers use?

Tools are necessary part if you want to become a Python developer. Here are the main tools that Python developers use.

Automation testing tools

Selenium is one of the most popular testing tools. And Python has it. It allows developers to build scripts in various languages like Ruby and Java. You can also run tests on any of the three major operating systems from any browser. 

Robot Framework is another test automation tool.  It works for web apps but also with iOS and Android test automation. Also, TestComplete is an automated testing program that requires a commercial license.

Data science tools

Scikit-Learn is an open-source tool. Many Python developers are using it for data mining and data analysis. 

Theano is a Python library. It is helpful for evaluating math computations. Such a library integrates tightly with other libraries for technical and scientific computing.

Keras is also another great library. It is very easy to use and well-suited to machine learning and deep learning. 

Web scraping tools

LXML is a Python-based tool. Beautiful Soup is a library that saves time for apps like screen scraping. Scrapy is an open-source Python framework that scans web pages and pulls data from them.

The jobs you can get with Python

Once you figure out how to become a Python developer, it’s time to choose your niche. A Python developer can have various job titles. The following is one of them:

  • Python developer;
  • Data scientist;
  • Full stack developer;
  • Data engineer;
  • Machine learning engineer. 

The specific job you'll be doing can vary depending on :

  • The industry;
  • Organization;
  • Scope of the function.

Your main job will be writing codes.  This way, you will build websites and apps or work with data and AI.

You can start freelancing as a Python developer or look for a job in a company. 

There are a bunch of jobs that need Python programming abilities. But, they all have one thing in common: great salary. This is most likely due to businesses' need for Python talent across various sectors.
