Hello World in Python

"The simplest things may seem insignificant, but in programming every beginning makes the difference between just dreaming and actually starting to build."

The Hello World program is the classic first step in any programming language.
In this tutorial, you will learn how to create it in Python, understand what it means, and discover how to expand this simple example into more advanced concepts.

What is Hello World?

"Hello World" is a traditional program that displays a message on the screen.
It is used as the first contact with a programming language because it is simple, straightforward, and helps confirm that everything is working correctly.

Your First Hello World in Python

Creating this program in Python is very easy—it only takes a single line of code:

print("Hello, World!")

When you run this program, the console will display:

Hello, World!

Code Explanation

• print() → is a built-in Python function that outputs information to the screen.
• "Hello, World!" → is a string of text. It is enclosed in quotes so that Python interprets it as literal text.

Common Errors

When starting out, it’s normal to make small mistakes. Some examples:

Writing without quotes:

print(Hello, World!)

Correct:

print("Hello, World!")

Using Print instead of print (Python is case-sensitive).

History of Hello World

The first documented use of Hello World was in the book "The C Programming Language" by Brian Kernighan and Dennis Ritchie in 1978. Since then, it has become the universal tradition for starting with any programming language.
