What are default values in Python functions?

Default values in Python functions allow you to set a default value for a parameter if no argument is provided.

Can you give me an example of how to use default values?

Sure! Here's a simple example:

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

If you call greet(), it will return 'Hello, Guest!'. If you call greet('Alice'), it will return 'Hello, Alice!'.

What happens if I provide a value for a parameter with a default value?

If you provide a value for a parameter with a default value, the provided value will override the default. For example, greet('Bob') will return 'Hello, Bob!'.

Are there any limitations to using default values?

Yes, you cannot use mutable default values like lists or dictionaries, as they can lead to unexpected behavior. It's best to use immutable types like integers or strings.
