Installing Python, Running First Program

Introduction

Are you ready to start coding with Python? This tutorial will help you install Python on your computer and run your very first program. Whether you’re a student or an aspiring developer, this is the first step in your Python journey.

What You Need Before You Begin

  • A computer with internet access
  • Basic knowledge of how to use your operating system
  • No programming experience needed!

Step 1: Downloading Python

Go to the Official Website

Visit python.org and click on the “Downloads” section. It will detect your OS and suggest the best version.

Choose the Right Version

Download the latest stable version. For most users, Python 3.x is recommended.

Step 2: Installing Python

Installing on Windows

Open the downloaded file. Make sure to check the box that says “Add Python to PATH” before clicking Install.

Installing on macOS/Linux

Mac users can install Python using the installer. Linux users can use the terminal command sudo apt install python3.

Check the Installation

Open your terminal or command prompt and type:

python --version

You should see something like Python 3.11.1. This means Python is installed correctly.

Step 3: Running Your First Python Program

Using IDLE

Python comes with a simple code editor called IDLE. Open it, type the code below, and press Enter:

print("Hello, world!")

You will see the output: Hello, world!

Using VS Code (Optional)

If you’re using Visual Studio Code, install the Python extension and run the same code in a new file with a .py extension.

Using Terminal

Open a terminal or command prompt, type python, then enter your code.

Common Errors and Fixes

  • ‘python’ not recognized: Reinstall and check the PATH option.
  • SyntaxError: Make sure your code is typed exactly like the example.
