What are the best practices for using *args and **kwargs in Python?

Using *args and **kwargs allows for flexible function arguments. Best practices include using them when necessary, documenting their use, and avoiding overuse to maintain code readability.

Can you give me an example of how to use them?

Sure! Here's a simple example:

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

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

This will output:

(1, 2, 3)
{'name': 'Alice', 'age': 30}

Avoid using them excessively, as it can make your code harder to understand. Also, be cautious about naming conflicts in **kwargs.
