How do I handle optional arguments in functions?

You can handle optional arguments in functions by using default values or by using the *args and **kwargs syntax in Python.

Can you give me an example of using default values?

Sure! Here's a simple example:

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

In this case, if you don't provide a greeting, it will default to 'Hello'.

What about using *args and **kwargs?

Using *args allows you to pass a variable number of positional arguments, while **kwargs allows for variable keyword arguments. Here's an example:

def example_function(*args, **kwargs):
    print(args)
    print(kwargs)

You can call it with any number of arguments!

Thanks! This is really helpful.
