Can you explain what is meant by the concept of a function in programming?

A function in programming is a named block of code that performs a specific task and can accept input data (arguments), as well as return a result. Functions help structure the program, reuse code, and improve readability.

Example of a function in Python:

def greet(name):
    return f"Hello, {name}!"

print(greet("Anna"))  # Outputs: Hello, Anna!
