What are default values in functions?

Default values in functions are predefined values that are used if no argument is provided when the function is called.

Can you give me an example of a function with default values?

Sure! Here's a simple example in Python:

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

In this case, if you call greet() without an argument, it will return 'Hello, Guest!'.

What happens if I provide an argument?

If you provide an argument, the function will use that value instead of the default. For example, greet('Alice') will return 'Hello, Alice!'.

Are there any limitations to using default values?

Yes, default values can only be specified for parameters that are at the end of the parameter list. You can't have a non-default parameter after a default one.
