What are parameters and arguments in Python?

Can you explain the difference between parameters and arguments in Python?

Sure! Parameters are the variables listed in a function's definition, while arguments are the actual values passed to the function.

Can you give me an example of a function with parameters and how to call it with arguments?

Absolutely! Here's a simple example:

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

You call it with an argument like this: greet('Alice').

What happens if I don't provide an argument for a parameter?

If the parameter has no default value, Python will raise a TypeError. You need to provide an argument when calling the function.

Can parameters have default values?

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

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

Now, calling greet() will use 'Guest' as the default name.
