How do I use variables in functions?

Can you explain how to use variables in functions?

Sure! Variables in functions are used to store data that can be used and manipulated within the function.

Can you give me an example of a function using variables?

Absolutely! Here's a simple example in Python:

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

In this function, 'name' is a variable.

What happens if I don't use variables?

Without variables, you would have to hard-code values, making your functions less flexible and reusable.

How do I pass multiple variables to a function?

You can pass multiple variables by separating them with commas in the function definition and when calling the function. For example:

def add(a, b):
    return a + b
