When should I use *args and **kwargs in Python?

Can you explain when to use *args and **kwargs in Python?

Sure! Use *args when you want to pass a variable number of non-keyword arguments to a function.

What about **kwargs?

**kwargs allows you to pass a variable number of keyword arguments. It's useful for functions that need to handle named parameters.

Can you give me an example of both?

Of course! Here's a simple example:

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

example(1, 2, 3, name='Alice', age=30)

This will output the positional arguments as a tuple and the keyword arguments as a dictionary.

That makes sense! Are there any best practices for using them?

Yes! Use *args for optional positional arguments and **kwargs for optional keyword arguments. Keep your function signatures clear.
