Hello, World!

Write your first Python program

Hello, World! — Your First Python Program

What Is It?

Every programming journey starts with one classic line: print("Hello, World!"). This tiny program does one thing — it displays text on the screen. But behind that single line, you're learning two fundamental concepts that will appear in every Python program you ever write.

The print() function tells Python "hey, show this to the user." Think of it like a messenger — you hand it a message, and it delivers it to the screen.

� **Fun fact:** "Hello, World!" has been the traditional first program since the 1970s, when Brian Kernighan used it in the C programming language book.

Syntax

python

print("Hello, World!")

Part	What it's called	What it does
`print`	Function name	Tells Python you want to output something
`(` `)`	Parentheses	The "call" operator — activates the function
`"Hello, World!"`	String literal	The message to display (text in quotes)

How It Works

When you run this program, Python does three things:

**Reads** the line of code from left to right

**Recognizes** `print` as a built-in function

**Executes** it, sending the text `Hello, World!` to the output window

Try it in the editor below — click Run Code and watch what happens!

python

print("Hello, World!")

� **Key point:** The quotes `"` are NOT part of the output. They tell Python where the text starts and ends. The output is just: `Hello, World!`

Why Use `print()`?

If you can't see what your program is doing, you're flying blind. print() is your window into the program's world. You'll use it for:

**Seeing results** — Did my calculation give the right answer?

**Debugging** — What value does this variable have right now?

**Communicating** — Show the user instructions, results, or messages

**Testing** — "Is this part of my code even running?"

Without print(), your code runs invisibly. With it, you can see everything.

Common Mistakes

❌ Wrong	Why	✅ Right
`Print("Hello")`	Python is case-sensitive — `print` is lowercase	`print("Hello")`
`print(Hello)`	Missing quotes — Python looks for a variable named `Hello`	`print("Hello")`
`print("Hello")` without parentheses	Parentheses are required to call a function	`print("Hello")`
`print('Hello')`	Single quotes work too, but be consistent	`print("Hello")`

Your Turn!

Write a program that prints your name and your favorite food, each on a separate line.

� **Hint:** Use two `print()` statements, one for each line!
