Can you explain what *args means in a function and how it works in Python?

In Python, *args is used in a function definition to pass a variable number of positional arguments. This means that the function can accept any number of arguments, which inside the function will be accessible as a tuple.

Example:

def greet(*args):
    for name in args:
        print(f"Hello, {name}!")

greet('Anna', 'Boris', 'Vika')

Output:

Hello, Anna!
Hello, Boris!
Hello, Vika!

Thus, *args allows writing more flexible functions that are not limited to a fixed number of input parameters.
