What are function parameters in Python?

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

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

Sure! Here's a simple example:

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

In this case, name is a parameter.

What happens if I don't provide a parameter when calling the function?

If you don't provide a parameter, Python will raise a TypeError, indicating that a required positional argument is missing.

Can parameters have default values?

Yes! You can set default values for parameters. For example:

def greet(name='Guest'):
    print(f'Hello, {name}!')

Now, if you call greet() without an argument, it will use 'Guest' as the default.
