Say “Hello!”

Welcome to Learn Python! This course is built for beginners who want to practice with real code from the very start. Whether you’re curious about coding or aiming for a tech career, Python is a great place to begin.

Computers don’t speak English naturally, but luckily, they’re fluent in Python and respond instantly when you speak their language!

Imagine you’re teaching your computer to say “Hello.” It’s simple, fun, and your first step toward mastering Python.

Our first Python conversation

Let’s start by printing a message to the screen. You can always take the AI mentor’s help for a better understanding!

• Action: Click the “Run” button above to see what happens.

• Instant output: Hello World

Your turn: Customize your greeting

Now, let’s personalize your greeting. Try changing the text inside the quotes ("Hello World") to something meaningful to you.
Maybe:

• Your name

• A favorite quote

• Something funny!

Let’s look at the following example:

Go ahead, edit it now, then click the “Run” button again.

Quick breakdown: What’s going on?

You just used Python’s print() function:

• print() is how Python shows you messages on the screen.

• To make Python display text, put it in quotes ("Like this!"). Numbers don’t need quotes—just write: 42. If you put quotes around a number, like "42", Python treats it as text.

• Quotes tell Python, “Hey, treat this as text.”
