How to Install Python on Windows, macOS, and Linux - Beginner's Guide

Python is an object-oriented, high-level programming language with integrated dynamic semantics primarily for web and app development. It is extremely attractive in the field of Rapid Application Development because it offers dynamic typing and dynamic binding options. The simplicity of Python sets it apart from other programming languages.

However, regardless of its versatility and ease of use, if you are new to programming, you might find the installation process a bit tricky. To put those worries to rest, this comprehensive guide will walk you through how to install Python on Windows, macOS, and Linux. Let's start.

Installing Python on Windows:

Firstly, you’ll need to download the Python installer. Go to the official Python website (https://www.python.org/), navigate to the 'Downloads' section, and click on the Windows installer. Typically, the site defaults to the version suitable for your operating system. However, ensure you choose the version you prefer.

• Once the installer is downloaded, run it. A dialog box subsequently opens.

• There's a checkbox at the bottom of the window captioned "Add Python to PATH". Be sure to check this box as it allows you to run Python commands from the Command Prompt.

• After that, click on "Install Now". Your Windows system should now start installing Python. This process could take a couple of minutes. Once the installation is done, click on “Close”.

You can confirm the installation by opening Command Prompt and typing 'Python'. If it is installed correctly, it responds with the Python version information. If not, it suggests that Python is not added to your PATH, or the installation was unsuccessful.

Installing Python on macOS:

Unlike Windows, macOS comes with a pre-installed version of Python. However, it might not be the latest release, so you still might want to download a newer version. Follow these steps:

• Just as with Windows, go to the official Python website, navigate to the 'Downloads' section, and select the macOS installer.

• Once the installer is downloaded, open it and follow the prompts to install Python.

• Once the installation is complete, open the Terminal application, type 'Python' and press enter. Your Mac should respond with the Python version information.

Installing Python on Linux:

Most Linux distributions come with Python pre-installed. However, it’s usually an older version. Therefore you may want to install the latest version. Here is how you do it:

• Open the terminal and type the following commands to update and upgrade any existing packages:

sudo apt-get update
sudo apt-get -y upgrade

• After that, download the prerequisites and the desired Python package using the following commands:

sudo apt-get install -y make build-essential libssl-dev zlib1g-dev libbz2-dev libsqlite3-dev
wget https://www.python.org/ftp/python/3.x.x/Python-3.x.x.tgz

• Replace "3.x.x" with your specific desired version.

• Once done, install Python using the following commands:

tar -xvf Python-3.x.x.tgz
cd Python-3.x.x/
./configure
make
sudo make install

Python is now successfully installed on your Linux distribution.

The process by which to install Python varies across different operating systems, including Windows, macOS, and Linux. However, with the above straightforward steps, the installation process should be a breeze.

With Python correctly installed, you can now leap into the world of programming. There’s a whole lot you can achieve, from basic scripting to web development, data analytics, Artificial Intelligence, and Machine learning. The possibilities are limitless! Unlock your potential today by taking a leap into the prosperous world of Python programming.
