# This is a simple Python program that greets the user

# First, we define a function called 'greet_user'
def greet_user():
    # Ask the user for their name
    name = input("What's your name? ")

    # Print a greeting message that includes the user's name
    print(f"Hello, {name}! Welcome to the world of programming.")

# Call the 'greet_user' function to execute the code
greet_user()
