How do function parameters work in Python?

In Python, function parameters are variables that allow you to pass data into functions. They can be required or optional.

Can you give me an example of a function with parameters?

Sure! Here's a simple example:

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

In this case, name is a parameter.

What happens if I don't provide a parameter?

If a parameter is required and you don't provide it, Python will raise a TypeError. You can set default values to make them optional.

How do I return multiple values from a function?

You can return multiple values by separating them with commas. For example:

def get_coordinates():
    return (10, 20)

This returns a tuple with two values.
