What are some examples of tuple unpacking in Python?

Tuple unpacking allows you to assign values from a tuple to multiple variables in a single statement. For example, if you have a tuple like coordinates = (10, 20), you can unpack it like this: x, y = coordinates.

Can you show me more complex examples?

Sure! For instance, if you have a list of tuples like points = [(1, 2), (3, 4), (5, 6)], you can unpack them in a loop: for x, y in points:. This allows you to access each point's coordinates directly.

What about unpacking with default values?

Great question! You can use the underscore _ as a placeholder for values you want to ignore. For example, a, _, c = (1, 2, 3) will unpack 1 into a, ignore 2, and unpack 3 into c.

Are there any limitations to tuple unpacking?

Yes, the number of variables must match the number of elements in the tuple. If they don't, you'll get a ValueError. For example, a, b = (1, 2, 3) will raise an error.
