Installing Python on Windows, macOS, and Linux

Python is a versatile and widely-used programming language, and installing it on different operating systems is straightforward. This guide will walk you through the installation process for Python on Windows, macOS, and Linux. Whether you are setting up a development environment or simply getting started with Python, these instructions will help you get Python up and running on your system.

1. Installing Python on Windows

Follow these steps to install Python on a Windows machine:

1. Download the Installer: Visit the official Python website at Python Downloads for Windows and download the latest Python installer.
2. Run the Installer: Double-click the downloaded installer to run it. Ensure you check the box that says "Add Python to PATH" before clicking "Install Now."
3. Verify the Installation: Open Command Prompt and type python --version to verify that Python has been installed correctly. You should see the Python version number.

2. Installing Python on macOS

To install Python on macOS, follow these steps:

1. Download the Installer: Go to the Python Downloads for macOS page and download the latest macOS installer.
2. Run the Installer: Open the downloaded .pkg file and follow the instructions to install Python.
