What is Python used for?

Clearly, Python is a popular and in-demand skill to learn. But what is python programming used for? We’ve already briefly touched on some of the areas it can be applied to, and we’ve expanded on these and more Python examples below. Python can be used for:  

1. AI and machine learning 

Because Python is such a stable, flexible, and simple programming language, it’s perfect for various machine learning (ML) and artificial intelligence (AI) projects. In fact, Python is among the favourite languages among data scientists, and there are many Python machine learning and AI libraries and packages available. 

If you’re interested in this application of Python, our Deep Learning and Python Programming for AI with Microsoft Azure ExpertTrack can help you develop your skills in these areas. You can discover the uses of Python and deep learning while boosting your career in AI. 

2. Data analytics 

Much like AI and machine learning, data analytics is another rapidly developing field that utilises Python programming. At a time when we’re creating more data than ever before, there is a need for those who can collect, manipulate and organise the information. 

Python for data science and analytics makes sense. The language is easy-to-learn, flexible, and well-supported, meaning it’s relatively quick and easy to use for analysing data. When working with large amounts of information, it’s useful for manipulating data and carrying out repetitive tasks. 

You can learn about data analytics using Python with our ExpertTrack, which will help you develop practical data analytics skills. 

3. Data visualisation 

Data visualisation is another popular and developing area of interest. Again, it plays into many of the strengths of Python. As well as its flexibility and the fact it’s open-source, Python provides a variety of graphing libraries with all kinds of features. 

Whether you’re looking to create a simple graphical representation or a more interactive plot, you can find a library to match your needs. Examples include Pandas Visualization and Plotly. The possibilities are vast, allowing you to transform data into meaningful insights. 

If data visualisation with Python sounds appealing, check out our 12-week ExpertTrack on the subject. You’ll learn how to leverage Python libraries to interpret and analyse data sets.
