Python is a powerful and widely-used programming language, known for its simplicity and ease of use. With a large and active community, there are many libraries and frameworks available for various tasks, making it a great choice for beginners and experienced developers alike.

Note that, in Ubuntu/Mac, python2 is still installed in parallel with python3, so you can use python2 if you want, but it's recommended to use python3 for the new projects as python2 reached end-of-life at the end of 2019.
