Introduction

When learning any programming language, the very first program you write is usually Hello World.

This simple program prints a message to the screen and confirms that your Python installation and environment are working correctly.

The Hello World Program

Here is the simplest Python program you can write:

print("Hello World")

How It Works

Let's break it down.

print()

print() is a built‑in Python function used to display output in the terminal or console.

print("Hello World")

When Python executes this line, it sends the text inside the parentheses to the screen.

"Hello World"

The text inside quotes is called a string. Strings represent text data in Python.

print("Hello World")
print("Python is fun")
print("Welcome to programming")

Each of these lines prints a different message.

Running the Program

To run this code:

1. Open your Python editor.
2. Create a file called: hello.py
3. Add the code:

print("Hello World")

Run the file. You should see the following output:

Hello World

Why Every Language Starts With Hello World

The Hello World program is used because it is:

• Simple
• Easy to understand
• A quick way to verify that your programming environment works

Every major programming language has a version of this program.

Try It Yourself

Modify the message and print your own text.

print("Hello, my name is Alex")
print("I am learning Python")
