How to Install Python and PIP on Ubuntu 26.04

Published: Last updated:

Introduction

Python is a high-level, interpreted programming language known for its readable syntax and versatile application across web development, data science, automation, and artificial intelligence. Unlike compiled languages that require explicit translation to machine code, Python executes code line by line, which accelerates development cycles and simplifies debugging. The language's extensive standard library provides ready-to-use modules for common tasks, from file handling to network communication. PIP (Pip Installs Packages) serves as Python's package manager, allowing developers to install and manage thousands of third-party libraries from the Python Package Index (PyPI).

This guide shows you how to install Python 3 and PIP on Ubuntu 26.04 and configure a virtual environment for project-specific dependency management.

Prerequisites

Before you start:

Update System Package Information

Before installing new software, refresh your system's package index to ensure you pull the latest available versions from Ubuntu repositories.

  • Update the package list from all configured repositories.

    console
    $ sudo apt update

    Output:

    Hit:1 http://archive.ubuntu.com/ubuntu noble InRelease
Get:2 http://archive.ubuntu.com/ubuntu noble-updates InRelease
Get:3 http://archive.ubuntu.com/ubuntu noble-security InRelease
Reading package lists... Done

Install Python

Ubuntu 26.04 comes with Python pre-installed, but you may need to ensure you have the latest version or install Python if it is missing.

  • Check if Python is already installed on your system.

    console
    $ python3 --version

    Output:

    Python 3.14.4

    If the above command shows an error:

    • Install Python using the following command. The python3 package installs the latest stable Python version available in Ubuntu repositories.

      console
      $ sudo apt install -y python3

      Output:

      Reading package lists... Done
Building dependency tree... Done
Reading state information... Done
python3 is already the newest version (3.12.3-0ubuntu1).
0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.

  • Install python3-venv, apackage that allows you to create virtual environment. This package provides the tools to create isolated Python environments for different projects.

    console
    $ sudo apt install -y python3-venv

    Output:

    Reading package lists... Done
Building dependency tree... Done
Reading state information... Done
The following NEW packages will be installed:
  python3-venv
0 upgraded, 1 newly installed, 0 to remove and 0 not upgraded.
Need to get 1,024 B of archives.
After this operation, 5,120 B of additional disk space will be used.

Install PIP

Python 3 installations on Ubuntu often include PIP, but you may need to install it separately as a standalone package.

  • Check if PIP is already available on your system.

    console
    $ pip3 --version

    Output:

    pip 25.1.1 from /usr/lib/python3/dist-packages/pip (python 3.14)

    If the above command shows an error:

    • Install PIP using the package manager.

      console
      $ sudo apt install -y python3-pip

      Output:

      Reading package lists... Done
Building dependency tree... Done
Reading state information... Done
The following NEW packages will be installed:
  python3-pip
0 upgraded, 1 newly installed, 0 to remove and 0 not upgraded.
Need to get 1,200 kB of archives.
After this operation, 4,500 kB of additional disk space will be used.

Create and Activate a Virtual Environment

Virtual environments isolate project dependencies, preventing conflicts between different Python projects that may require different package versions. This practice represents standard Python development workflow.

  • Create a new directory for your Python project.

    console
    $ mkdir python-demo

  • Navigate into the new project directory.

    console
    $ cd python-demo

  • Create a new virtual environment named venv inside your project directory.

    console
    $ python3 -m venv venv

  • Activate the virtual environment.

    console
    $ source venv/bin/activate

  • Verify that your active Python environment uses the virtual environment's interpreter.

    console
    (venv) $ which python3

    Output:

    /home/your_username/python-demo/venv/bin/python3

Notice that your shell prompt now shows (venv) before the regular prompt, indicating your active Python environment.

Install Python Packages with PIP

With your virtual environment active, install some popular Python packages to test PIP functionality.

  • Install the requests library. This package simplifies making HTTP requests to web servers and APIs.

    console
    (venv) $ pip install requests

    Output:

    Collecting requests
Downloading requests-2.32.3-py3-none-any.whl (64 kB)
Collecting charset_normalizer
Downloading charset_normalizer-3.4.1-cp312-cp312-manylinux_2_17_x86_64.manylinux2014_x86_64.whl (149 kB)
Collecting urllib3
Downloading urllib3-2.4.0-py3-none-any.whl (128 kB)
Installing collected packages: urllib3, charset_normalizer, requests
Successfully installed charset_normalizer-3.4.1 requests-2.32.3 urllib3-2.4.0

  • List all active packages in your active Python environment and confirm that the requests library exists.

    console
    (venv) $ pip list

    Output:

    Package            Version
------------------ ---------
charset-normalizer 3.4.1
pip                25.0.1
requests           2.32.3
urllib3            2.4.0

  • Generate a requirements file that captures all packages and their versions. This file allows others to recreate the exact same environment.

    console
    (venv) $ pip freeze > requirements.txt

  • Display the contents of the generated requirements file.

    console
    (venv) $ cat requirements.txt

    Output:

    charset-normalizer==3.4.1
requests==2.32.3
urllib3==2.4.0

Create a Test Python Application

Build a simple Python script that uses the installed requests library to fetch data from a public API.

  • Create a new api_demo.py file using the nano text editor.

    console
    (venv) $ nano api_demo.py

  • Add the following Python code to fetch and display a random joke from an online API.

    Python
    import requests

def fetch_random_joke():
    url = 'https://official-joke-api.appspot.com/random_joke'

    try:
        response = requests.get(url)
        response.raise_for_status()
        joke_data = response.json()

        print(f"Here's a random joke for you:")
        print(f"Question: {joke_data['setup']}")
        print(f"Punchline: {joke_data['punchline']}")

    except requests.exceptions.RequestException as error:
        print(f"Failed to fetch joke: {error}")

if __name__ == '__main__':
    fetch_random_joke()

  • Save and close the api_demo.py file by pressing Ctrl + X, Y then Enter.

  • Run the Python script to test your environment.

    console
    (venv) $ python3 api_demo.py

    Output:

    Here's a random joke for you:
Question: What do you call a fake noodle?
Punchline: An impasta.

Your Python environment works correctly with third-party packages.

Deactivate the Virtual Environment

When you finish working on a project, deactivate the virtual environment to return to your system's global Python environment.

  • Exit the virtual environment.

    console
    (venv) $ deactivate

  • Verify that you have left the virtual environment by checking that (venv) no longer appears in your prompt.

    console
    $ which python3

    Output:

    /usr/bin/python3

Conclusion

In this guide, you have installed Python 3 and PIP on Ubuntu 26.04, created and activated a virtual environment for dependency isolation, installed third-party packages using PIP, and built a functional Python script that consumes a web API. Now that you have Python configured properly, consider exploring web frameworks like Fast API, Django, Flask to build full-stack applications, or dive into data science libraries such as NumPy and Pandas for data analysis projects.
