How to Print “Hello, World!” in Python 3: A Beginner’s Guide

Learning Python often begins with a simple yet powerful exercise: printing “Hello, World!” to the screen. This one-liner doesn’t just display text—it’s your first step toward mastering Python programming. Whether you’re brand new to coding or brushing up on Python basics, running this program confirms that your environment is set up correctly and introduces you to the print() function, one of the most frequently used commands in Python.

In this guide, we’ll explore multiple ways to run your first Python program—from scripts and the interactive shell to browser-based IDEs and IDLE. By the end, you’ll know exactly how to print your first line of Python code on any system.

Prerequisites

Before you begin, make sure you have the latest version of Python 3 installed. You can download it from the official Python website. Documentation for the print() function is available at docs.python.org.

Method 1: Run a Python Script (Recommended)

Running Python code from a script is the most common and reliable approach.

Step 1: Create a new file named hello_world.py.

Step 2: Add the following line of code:

print("Hello, World!")

Step 3: Open a terminal or command prompt.

Step 4: Navigate to the folder where your script is saved:

cd path/to/your/folder

Step 5: Run the script:

• Windows (reliable): py hello_world.py
• Windows (if Python is on PATH): python hello_world.py
• macOS/Linux: python3 hello_world.py

Step 6: If everything is correct, the output will be:

Hello, World!

Method 2: Use the Interactive Python Shell (REPL)

If you prefer experimenting directly, you can use Python’s built-in REPL (Read–Eval–Print Loop).

Step 1: Open a terminal or command prompt.

Step 2: Start the Python shell:

• Windows: py -3
• macOS/Linux: python3

Step 3: Type your code and hit Enter:

print("Hello, World!")

Output:

Hello, World!

Step 4: Exit the shell by typing:

exit()

Method 3: Run Python in a Browser (No Installation Required)

If you don’t want to install Python locally, you can use a browser-based IDE like Replit, Google Colab, or Jupyter Notebook.

Step 1: Open any online Python IDE.
Step 2: Create a new file or notebook cell.
Step 3: Add and run:

print("Hello, World!")

Your output will instantly appear in the browser.

Method 4: Run Python with IDLE

Python also comes bundled with IDLE, a beginner-friendly editor available on Windows and macOS.

Step 1: Launch IDLE from your Start Menu or Applications folder.
Step 2: Open a new file (File → New File).
Step 3: Add your program:

print("Hello, World!")

Step 4: Save it as hello_world.py.
Step 5: Run it using Run → Run Module or simply press F5.

Common Issues and Quick Fixes

• Use Python 3 syntax: Always include parentheses with print(). In Python 2, print was a statement without them.
• Windows launcher tip: Use py on Windows for the most reliable execution. If python doesn’t work, try py hello_world.py.
• Nothing prints? Make sure you’re in the correct directory, and confirm the file name isn’t python.py.
• String flexibility: Python supports single, double, or triple quotes. For example: print('Hello, World!') print("Hello, World!")
• Indentation matters: Python uses indentation instead of braces. While this example is one line, remember to use four spaces when writing blocks.

Conclusion

Printing “Hello, World!” is more than just a tradition—it’s your first step into the world of Python programming. Whether you choose to run a script, use the REPL, experiment in the browser, or try IDLE, the process helps you confirm your setup and introduces you to Python’s clean and readable syntax.

Keep your hello_world.py script handy—you’ll be building on this foundation as you explore variables, loops, functions, and more. This simple line of code marks the beginning of your journey into coding with Python.
