What are the best practices for tuple unpacking in Python?

Tuple unpacking in Python allows you to assign values from a tuple to multiple variables. Best practices include using parentheses for clarity, unpacking only when the number of variables matches the tuple length, and using the underscore (_) for unused values.

Can you give me an example of tuple unpacking?

Sure! Here's a simple example:

coordinates = (10, 20)
x, y = coordinates
print(x, y)  # Output: 10 20

What should I avoid when unpacking tuples?

Avoid unpacking tuples with a different number of variables than elements in the tuple, as it will raise a ValueError. Also, be cautious with nested tuples to ensure clarity.

Are there any performance considerations?

Tuple unpacking is generally efficient, but if you're unpacking large tuples in a loop, consider the overhead. Always measure performance if it's a critical part of your code.
