🎤 Model Answer spoken

This function is called greet_user. It takes one parameter called name, which represents the user's name.

Inside the function, a variable called message is created. The code combines the text "Hello, " with the value of the name parameter using string concatenation.

After that, the function returns the completed message. Finally, the print() statement calls the function with the value "Robbie" and displays the result in the console.

The final output would be Hello, Robbie.
