How To Install Python 3.11 on Ubuntu

1. Method 1 – Install Python 3.11 on Ubuntu from deadsnakes PPA

   The deadsnakes PPA provides the simplest method to install Python 3.11 on Ubuntu 22.04|20.04|18.04. It also enables users to receive continued updates, bug fixes, and security updates. A big thumbs up to this custom PPA!
   First, install the required dependency packages:
   
   sudo apt install software-properties-common -y
   
   Add the deadsnakes PPA to the APT package manager sources list.
   sudo add-apt-repository ppa:deadsnakes/ppa
   
   Proceed as shown:

   To install 3rd-party Python modules, you should use the common Python packaging tools. For an introduction into the Python packaging ecosystem and its tools, refer to the Python Packaging User Guide:
   https://packaging.python.org/installing/
   
   Sources
   =======
   The package sources are available at:

   Nightly Builds
   ==============
   
   For nightly builds, see ppa:deadsnakes/nightly https://launchpad.net/~deadsnakes/+archive/ubuntu/nightly
   More info: https://launchpad.net/~deadsnakes/+archive/ubuntu/ppa

   Press Enter to continue. Once the PPA has been added, you can install Python 3.11 on Ubuntu using the commands:
   
   sudo apt install python3.11
   
   Verify the installation:
   
   $ python3.11 u002du002dversion
   Python 3.11.1
   
   

2. Method 2 – Install Python 3.11 on Ubuntu from source

   This is an alternative method of installing Python 3.11 on Ubuntu Linux system. With this method, you are guaranteed the latest Python Version. The only problem with this method is that you will not be able to receive continued updates, bug fixes, and security updates through the APT package manager.
   
   Begin by installing the packages required to build Python 3.11 from the source.
   
   sudo apt update u0026u0026 sudo apt install build-essential zlib1g-dev libncurses5-dev libgdbm-dev libnss3-dev libssl-dev libreadline-dev libffi-dev libsqlite3-dev wget libbz2-dev pkg-config -y
   
   Once the packages have been installed, download the latest available Python 3.11 gzipped tarball from the Python official release page.
   You can still download the tarball using wget:
   
   wget https://www.python.org/ftp/python/3.11.1/Python-3.11.1.tgz
   
   Extract the downloaded archive:
   
   tar -xf Python-3.11.*.tgz
   
   Now navigate into the directory:
   
   cd Python-3.11.*/
   
   We will check if the required dependencies are met and optimize the binary with the command:
   
   ./configure u002du002denable-optimizations
   
   Sample Output:
   
   checking build system type… x86_64-pc-linux-gnu
   checking host system type… x86_64-pc-linux-gnu
   checking for Python interpreter freezing… ./_bootstrap_python
   checking for python3.11… no
   checking for python3.10… no
   checking for python3.9… no
   checking for python3.8… python3.8
   checking Python for regen version… Python 3.8.10
   checking for pkg-config… /usr/bin/pkg-config
   checking pkg-config is at least version 0.9.0… yes
   checking for u002du002denable-universalsdk… no
   checking for u002du002dwith-universal-archs… no
   checking MACHDEP… u0022linuxu0022
   checking for gcc… gcc

   config.status: creating Modules/ld_so_aix
   config.status: creating pyconfig.h
   configure: creating Modules/Setup.local
   configure: creating Makefile
   
   Once checked, start the build process with the command below. We have used -j to provide the number of cores available on the system, this makes the build process faster:
   
   make -j $(nproc)

   Note: Building Python from source can take a long time, depending on your system. You can adjust the number passed to the -j option in the make command to specify the number of parallel build jobs to run, which can speed up the build process.
   Once the build process is complete, install Python 3.11 with the command:
   
   sudo make altinstall
   
   We have used altinstall is used instead of install  to keep the default Python binary path in /usr/bin/python.

3. Install Python Extensions on Ubuntu 22.04|20.04|18.04

   Python modules are important since they add functionality to Python. These modules can be installed using the  Python Package manager (PIP).
   Install PIP on Ubuntu 22.04|20.04|18.04:
   
   sudo apt install python3-pip
   
   Now use PIP to install any module. The command to use has the syntax:
   
   sudo pip install module-name
   
   For example:
   
   sudo pip install mpesa
   
   Sample output:
   
   Collecting mpesa
   Downloading mpesa-0.0.1.tar.gz (2.4 kB)
   Preparing metadata (setup.py) … done
   Requirement already satisfied: pip in /usr/lib/python3/dist-packages (from mpesa) (22.0.2) Requirement already satisfied: requests in /usr/lib/python3/dist-packages (from mpesa) (2.25.1) Building wheels for collected packages: mpesa

   WARNING: Running pip as the ‘root’ user can result in broken permissions and conflicting behaviour with the system package manager. It is recommended to use a virtual environment instead: https://pip.pypa.io/warnings/venv
   
   You can list all the installed modules using the command;
