Step 1: Installing Python

Python can be installed on Windows, macOS, and Linux. Here’s a step-by-step guide for each platform:

1.1 Installing Python on Windows

1. Download Python: Go to the official Python website and download the latest version for Windows.

2. Run the Installer:

   • Double-click the downloaded installer.

   • Check the box that says "Add Python to PATH" (this is crucial for running Python from the command line).

   • Click "Install Now."

3. Verify Installation:

   • Open Command Prompt.

   • Type python --version and press Enter. You should see the installed Python version.

1.2 Installing Python on macOS

1. Check Pre-installed Version:

   • macOS often comes with Python pre-installed.

   • Open Terminal and type python3 --version to check.

2. Download Latest Version:

   • If you want the latest version, download it from Python’s website.

3. Install Using Homebrew (Optional):

   • Install Homebrew if not already installed: /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"

   • Install Python: brew install python3.

1.3 Installing Python on Linux

1. Check Installed Version:

   • Open Terminal and type python3 --version.

2. Install via Package Manager:

   • For Ubuntu/Debian: sudo apt update && sudo apt install python3

   • For Fedora: sudo dnf install python3

Step 2: Setting Up an IDE

An Integrated Development Environment (IDE) simplifies coding by providing features like syntax highlighting, debugging tools, and project management. Let’s explore some popular options.

2.1 PyCharm

PyCharm is a powerful IDE specifically designed for Python development.

Installation Steps:

1. Download PyCharm:

   • Visit JetBrains PyCharm and download the Community (free) edition.

2. Install PyCharm:

   • Run the installer and follow the prompts.

3. Configure PyCharm:

   • On first launch, set up the theme and keymap.

   • Create a new project and select the Python interpreter.

Writing Your First Program in PyCharm:

Run the program using the green play button.

2.2 Visual Studio Code (VS Code)

VS Code is a lightweight, versatile code editor that supports Python through extensions.

Installation Steps:

1. Download VS Code:

   • Go to Visual Studio Code and download the installer for your platform.

2. Install Python Extension:

   • Open VS Code and go to the Extensions Marketplace (Ctrl+Shift+X).

   • Search for "Python" and install the official Microsoft extension.

3. Configure Python Interpreter:

   • Press Ctrl+Shift+P, type “Python: Select Interpreter”, and choose your Python installation.

Writing Your First Program in VS Code:

Run the program using the Run button or Ctrl+F5.

2.3 Jupyter Notebook

Jupyter Notebook is ideal for data analysis, visualization, and interactive coding.

Installation Steps:

1. Install Jupyter:

   • Open Command Prompt or Terminal.

   • Install Jupyter using pip: pip install notebook.

2. Launch Jupyter Notebook:

   • Type jupyter notebook in the terminal to start the server.

   • A web interface will open in your default browser.

Writing Your First Program in Jupyter Notebook:

1. Create a new notebook.

2. Write the following code in a cell and run it:
