How can I use lists in functions effectively?

You can pass lists as arguments to functions, allowing you to manipulate and process the data within the function.

Can you give me an example of a function that uses a list?

Sure! Here's a simple example:

def sum_list(numbers):
    return sum(numbers)

This function takes a list of numbers and returns their sum.

What if I want to modify the list inside the function?

You can modify the list directly since lists are mutable in Python. For example:

def append_to_list(my_list, item):
    my_list.append(item)

Are there any best practices for using lists in functions?

Yes! It's best to avoid modifying the original list unless necessary. Consider returning a new list instead.
