Think of a program like a set of instructions you give to a computer. You tell it what to do, and it follows your orders precisely. But how do you speak the language of computers? That’s where programming languages come in.
Imagine you’re trying to teach a robot how to make a sandwich. You can’t just shout instructions at it; you need to speak in a way it understands. Programming languages are like special languages designed for computers, allowing us to communicate with them and give them instructions.
There are many different programming languages, each with its own unique vocabulary and grammar. Some popular languages include Python, Java, and JavaScript.
Traditionally, the very first program most people write is a simple one called “Hello World!”. This program just displays the words “Hello World!” on the screen. While it might seem basic, it’s a huge milestone! It means you’ve successfully written your first set of instructions that a computer can understand.
Let’s see how this program looks in Python:
print("Hello World!")
Here’s how this simple program works:
To run your program, you need a text editor to write your code and a programming environment to execute it. There are many free options available online, like Repl.it or Google Colab.
Once you’ve written your “Hello World!” program, you can save it and then click the “Run” button in your programming environment. Watch as your program comes to life and “Hello World!” appears on the screen!
Learning to write “Hello World!” is just the beginning. You can then go on to create much more complex programs, like games, websites, and even powerful data analysis tools.
But how do you learn more?
Now that you understand the basics, why not try writing your own “Hello World!” program? It’s a fun and rewarding experience that opens up a whole new world of possibilities!

Don’t forget: programming is all about experimentation and learning from mistakes. Have fun and enjoy the journey!
