Step 2: Download latest Python 3.8 Archive

Type the below command to download the latest archive of Python 3.8 archive.

sudo yum -y install wget
wget https://www.python.org/ftp/python/3.8.1/Python-3.8.1.tgz

Now, extract the downloaded pages by typing

tar xvf Python-3.8.1.tgz

Move to the Python directory.

cd Python-3.8*/

Step 3: Installing Python 3.8 on CentOS 8

Let’s start installation setup by running the configure script

./configure --enable-optimizations

Start the compilation of Python 3.8 on CentOS 8

sudo make install

Today, let’s have a look at getting the latest version of Python in our Linux distro.

Installing Python

There are 2 available ways you can get Python – from the repo of the distro and building from the source. Some distros like Ubuntu, Debian, and Fedora etc. comes up with Python in their software repository. In the case of others, it’s the best to install Python from source.

Installing from distro repository

Run the following commands according to your Linux distro –

• Ubuntu

sudo apt update && sudo apt upgrade -y

# Python 3
sudo apt install python3
OR
sudo apt install python3.7

# Python 2
sudo apt install python

• Debian

sudo apt-get install python3

• OpenSUSE

sudo zypper install python3

• Fedora

sudo dnf install python37

• Arch Linux

sudo pacman -S python

Installing Python from source

At first, make sure that your system has all the required dependencies to build Python from source –

• Ubuntu

sudo apt install make build-essential libssl-dev zlib1g-dev libbz2-dev

• Debian

sudo apt-get install make build-essential libssl-dev zlib1g-dev libbz2-dev

• OpenSUSE

sudu zypper install -t pattern devel_C_C++

• CentOS

sudo yum update
sudo yum -y groupinstall development
sudo yum -y install zlib-devel

Now, download the latest source package of Python –

wget https://www.python.org/ftp/python/3.7.0/Python-3.7.0.tar.xz

Extract the archive –

tar -xvf Python-3.7.0.tar.xz

Build the source –

./configure --enable-optimizations --with-ensurepip=install
make -j4
make test

Install the package –

sudo make altinstall

Testing Python

Depending on the version you installed, run the following command(s) to verify that Python is available system-wide.

python --version
OR
python3 --version

Voila! Python is installed successfully!
