What is tuple unpacking in Python functions?

Can you explain what tuple unpacking is in Python functions?

Sure! Tuple unpacking allows you to assign values from a tuple to multiple variables in a single statement.

Can you give me an example of how to use tuple unpacking in a function?

Of course! Here's a simple example:

def return_tuple():
    return (1, 2, 3)

a, b, c = return_tuple()
print(a, b, c)  # Output: 1 2 3

What happens if the number of variables doesn't match the tuple size?

If the number of variables doesn't match, you'll get a ValueError. For example, if you try to unpack a tuple of three values into two variables, it will raise an error.

Are there any best practices for using tuple unpacking?

Yes! It's best to use tuple unpacking when the number of elements is known and matches the number of variables, to avoid errors.
