What are mutable and immutable types in Python?

Can you explain the difference between mutable and immutable types in Python?

Sure! In Python, mutable types can be changed after they are created, like lists and dictionaries. Immutable types, like tuples and strings, cannot be changed.

Can you give me examples of both mutable and immutable types?

Absolutely! A list is a mutable type because you can add or remove items. A string is immutable; once created, you can't change its characters.

What happens if I try to change an immutable type?

If you try to change an immutable type, Python will raise an error. For example, attempting to modify a string will result in a TypeError.

Are there any performance differences between mutable and immutable types?

Yes, immutable types can be more memory efficient and faster for certain operations since they can be cached. Mutable types may require more memory due to their ability to change.
