How do I handle optional parameters in my function?

How do I handle optional parameters in my function?

You can handle optional parameters by providing default values or using techniques like argument unpacking.

Can you show me an example in Python?

Sure! Here's a simple example:

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

In this case, 'greeting' is optional.

What if I want to allow multiple optional parameters?

You can add more optional parameters by providing default values for each one. For example:

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

Are there any best practices for using optional parameters?

Yes, it's best to keep the number of optional parameters to a minimum to avoid confusion, and document them clearly.
