What are function parameters in Python 3?

Can you explain what function parameters are in Python 3?

Sure! Function parameters are variables listed inside the parentheses in a function definition. They allow you to pass data into functions.

How do I define a function with parameters?

You define a function with parameters by including them in the parentheses after the function name. For example: def my_function(param1, param2):.

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

Absolutely! Here's a simple example:

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

You can call it with greet('Alice').

What happens if I don't provide the required parameters?

If you don't provide the required parameters, Python will raise a TypeError, indicating that the function is missing required positional arguments.
