Can you please explain why it returns only one output?

Hi Timi,

Good question. It depends on how the function is defined.

Here’s your example:

def greet(message):
    print(message)

greet('Hi', 'Hello')

In this case, the function greet is defined to accept only one argument — message. But when you call it with two arguments ('Hi', 'Hello'), Python throws an error:

TypeError: greet() takes 1 positional argument but 2 were given

So actually, it doesn’t return one output — it raises an error because you passed more arguments than expected.

If you want the function to handle multiple messages, you can use *args, like this:

def greet(*messages):
    for message in messages:
        print(message)

greet('Hi', 'Hello')

Output:

Hi  
Hello

Using *messages lets the function accept any number of arguments and print each one.

If you have more questions, I am here to help.
