How To Install Python On Linux

In this article, we will explain how to install Python on Linux. Python is definitely one of the most infamous programming languages. Python is very easy to learn due to the simple syntax, and high readability. This makes it a top choice among developers. Apart from that, Python’s versatility also makes it a preferred programming language.

Let us now go through the steps to install the latest version of Python on Linux. We will be installing Python on the Debian distribution of Linux.

1. Installing Development Packages

Before we start installing Python, we need to install the development packages. And, these packages include headers related to the libraries. First, run the below command to get the updated information related to the updated version of packages and dependencies.

sudo apt update

Then, run the below command to install the development packages necessary to build Python.

sudo apt install build-essential zlib1g-dev \
libncurses5-dev libgdbm-dev libnss3-dev \
libssl-dev libreadline-dev libffi-dev curl

2. Downloading the Latest Version of Python

We are going to be installing the latest version of Python from the official Python website. The version to be installed is 3.10.2. Wget is a command utility in Linux that can download files. And, here we are going to be downloading the XZ compressed source tarball.

7. Creating a virtual environment

This is an optional step. Virtual environment is a feature of Python which helps you keep your packages or project directory separate. It’s commonly known as venv.

To create the virtual environment, you use the below command. Here’s the virtual environment named environment is created.

python3.10 -m venv myenvironment

And, then you can activate the environment by executing the following command. In the console, you will then be logged in via the virtual environment.

source myenvironment/bin/activate

You can simply deactivate the environment by executing the deactivate command as shown below.
