How to Install Python on Ubuntu Server: A Comprehensive Guide

🐍 Introduction: Welcoming Ubuntu Users

Welcome, Ubuntu users! Are you ready to explore the world of Python programming? If you’re looking to install Python on your dedicated server or Virtual Private Server (VPS), you’re in the right place. Python is a popular, high-level programming language that’s widely used for web development, data analysis, artificial intelligence, and more. In this article, we’ll cover the steps you need to take to install Python on Ubuntu Server, one of the most popular Linux distributions out there.

👉 Step 1: Updating Ubuntu Server

Before we start, it’s important to update your Ubuntu Server to the latest version. This will ensure that you have the latest security patches and bug fixes. Here’s how you can update your server:

Command	Description
sudo apt-get update	Updates the package list
sudo apt-get upgrade	Updates all installed packages

👉 Step 2: Installing Python on Ubuntu Server

Now that your server is up-to-date, you can proceed with the installation of Python. Ubuntu Server comes with Python pre-installed, but it’s usually an older version. We recommend installing the latest stable version, which is Python 3. Here’s how to install Python 3 on Ubuntu Server:

Command	Description
sudo apt-get install python3	Installs Python 3

👉 Step 3: Verifying the Installation

Once the installation is complete, you can verify that Python 3 is installed correctly by running the following command:

Command	Description
python3 --version	Displays the Python version

If you see the Python version number, everything has been installed correctly.

👉 Step 4: Setting Up a Virtual Environment

It’s good practice to create a virtual environment for your Python projects. This will ensure that your project dependencies are isolated from the system-wide packages. Here’s how you can create a virtual environment:

Command	Description
sudo apt-get install python3-venv	Installs the venv module
python3 -m venv myenv	Creates a virtual environment named “myenv”
source myenv/bin/activate	Activates the virtual environment

Your terminal prompt should now start with “(myenv)” to indicate that you’re working inside the virtual environment.

👉 Step 5: Installing Packages with pip

Now that you’re inside the virtual environment, you can install packages with pip. Pip is the package installer for Python and comes pre-installed with Python 3. Here’s how you can install a package:

Command	Description
pip install <package_name>	Installs a package

Replace “<package_name>” with the name of the package you want to install. For example, to install the popular NumPy package, you can run:

Command	Description
pip install numpy	Installs the NumPy package
