Python is the fastest growing major general-purpose programming language. There are many reasons for this, such as its readability and flexibility, ease of learning and use, reliability and efficiency.
There are two major versions of Python in use today – 2 and 3 (Python's present and future); the former does not see new major versions, while the latter is under active development and has had many stable releases over the past few years. The latest stable version of Python 3 is version 3.11.
On newer Ubuntu versions, Python 3.10 or Python 3.8 comes preinstalled, while older Ubuntu versions do not.
In this article, we will explain how to use deadsnakes PPA to install the latest Python 3.11 version on all Ubuntu versions through apt package manager.
To install the latest version of Python from source on all major Linux distributions, check out this guide:
Install
To install the latest Python 3.11 version, you can use the "deadsnakes" team PPA, which contains the latest Python version packaged for Ubuntu.
$ sudo add-apt-repository ppa:deadsnakes/ppa
$ sudo apt update
$ sudo apt install python3.11
If you want to install a specific Python version or multiple versions of Python on your Ubuntu system, just run the following command and enter the Python version number as shown.
$ sudo apt install python3.10
$ sudo apt install python3.9

OR
exit()
Set default version
If you have multiple versions of Python installed on your Ubuntu system and you only want to set one version as the default, then you need to perform some extra steps as shown.
$ python3 --version
$ sudo update-alternatives --install /usr/bin/python3 python3 /usr/bin/python3.10 1
$ sudo update-alternatives --install /usr/bin/python3 python3 /usr/bin/python3.11 2
$ sudo update-alternatives --config python3
$ python3 --version
that's all! In this short article, we explain how to install Python 3.11 in Ubuntu through apt package manager.
