What are mutable and immutable types in Python?

What are mutable and immutable types in Python?

In Python, mutable types can be changed after creation, like lists and dictionaries, while immutable types cannot, like tuples and strings.

Can you give me examples of mutable and immutable types?

Sure! A list is mutable: you can add or remove items. A tuple is immutable: once created, you can't change its elements.

Why would I use immutable types?

Immutable types are useful for ensuring data integrity and can be used as keys in dictionaries, unlike mutable types.

Are there performance differences between mutable and immutable types?

Yes, immutable types can be more memory efficient and faster in certain operations since they don't require additional memory allocation.
