Python is the fastest-growing major general-purpose programming language. There are a number of reasons attributed to this, such as its readability and flexibility, ease to learn and use, reliability, and efficiency as well.
There are two major Python versions being used – 2 and 3 (the present and future of Python); the former will see no new major releases, and the latter is under active development and has already seen a lot of stable releases over the last few years. The latest stable release of Python 3 is version 3.11.
On newer Ubuntu releases, Python 3.10 or Python 3.8 is pre-installed, which is not the case for older Ubuntu versions.
In this article, we will explain how to install the latest Python 3.11 version on all Ubuntu releases via the apt package manager using deadsnakes PPA.
