What is destructuring in Python and how can I use it effectively?

Destructuring in Python allows you to unpack values from data structures like lists and dictionaries into variables. It's a concise way to assign multiple variables at once.

Can you give me an example of destructuring with a dictionary?

Sure! If you have a dictionary like data = {'name': 'Alice', 'age': 30}, you can destructure it like this: name, age = data.values(). This assigns 'Alice' to name and 30 to age.

What about destructuring nested data structures?

For nested structures, you can do something like this: data = {'user': {'name': 'Alice', 'age': 30}} and then use {'name': name, 'age': age} = data['user'] to extract the values.

Are there any performance considerations I should be aware of?

Generally, destructuring is efficient, but if you're working with very large data structures, consider the overhead of unpacking. Always profile if performance is critical.
