What is Python?

Python is a high-level, open source, interpreted programming language known for its simplicity and readability. It's widely used in various fields like web development, data science, artificial intelligence, and more.

Why is Python used in health and care?

Because Python is open source, multi-purpose, has extensive libraries for statistics, data science, healthcare analytics and wider research. It’s also got a vibrant and helpful community meaning it’s easier to get started with an abundance of free training resources. Python is specifically mentioned in the Goldacre Review as one of the open source tools colleagues in Health and Care should be considering using.

What is open source?

Open source software like Python, is software which is released under a permissive licence which allows for anyone to freely access, use, modify, and share the source code of the software for any purpose. In practice, this means it is freely available to those in the NHS and beyond, without cost, and has a large user base. While Python itself is open source, you can choose whether (and are strongly encouraged) to release your own code as open source, in line with government policy such as Data Saves Lives, the NHS Service Standard and the Goldacre review.

Why should you learn Python?
Learning Python opens doors to a wide range of career opportunities due to its versatility and extensive use in industries like web development, data analysis, machine learning, automation, and scientific computing. Its syntax is clear and easy to understand, making it an excellent language for beginners. Python, along with R, is explicitly mentioned in the Goldacre review.
  • Associated with govt policy documents such as Data Saves Lives, encouraging move towards open source tools.
