What is the difference between mutable and immutable types in Python?

What is the difference between mutable and immutable types in Python?

In Python, mutable types can be changed after creation, while immutable types cannot. For example, lists are mutable, but tuples are immutable.

Can you give me examples of mutable and immutable types?

Sure! Mutable types include lists, dictionaries, and sets. Immutable types include strings, tuples, and frozensets.

Why would I use immutable types?

Immutable types are useful for ensuring data integrity, as they cannot be altered. They can also be used as keys in dictionaries.

Are there performance benefits to using immutable types?

Yes, immutable types can lead to performance optimizations, especially in multi-threaded environments, as they are inherently thread-safe.
