2.1 Installing Python – Step-by-Step Guide for Different Platforms

Welcome to the practical side of our Python journey! In this lesson, we’ll walk through the essential process of installing Python on various platforms. Whether you’re using Windows, macOS, or Linux, we’ve got you covered with a detailed, step-by-step guide.

Why is Installation Important?

Before we dive into the installation process, let’s understand the importance of setting up Python correctly. A proper installation ensures you have access to the Python interpreter, libraries, and development tools required for coding. It’s the first crucial step in your Python programming adventure.

Windows Installation:

  1. Download Python Installer:
    • Navigate to the official Python website.
    • Select the latest version compatible with your system (32-bit or 64-bit).
    • Download the installer executable (.exe) file.
  2. Run the Installer:
    • Locate the downloaded file and double-click to run the installer.
    • Check the box that says “Add Python to PATH” during installation.
    • Follow the on-screen instructions to complete the installation.
  3. Verify Installation:
    • Open the Command Prompt and type python --version to confirm the installation.

macOS Installation:

  1. Homebrew Installation (Optional but Recommended):
    • Open the Terminal.
    • Install Homebrew by pasting the command from the official Homebrew website.
  2. Install Python using Homebrew:
    • Type brew install python in the Terminal and press Enter.
    • Homebrew will handle the installation process.
  3. Verify Installation:
    • In the Terminal, type python3 --version to confirm the installation.

Linux Installation:

  1. Update Package Manager:
    • Open the Terminal.
    • Run sudo apt-get update (for Debian-based systems) or the equivalent command for your package manager.
  2. Install Python:
    • Run sudo apt-get install python3 (for Debian-based systems) or the equivalent command for your package manager.
  3. Verify Installation:
    • In the Terminal, type python3 --version to confirm the installation.
