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

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

Can you give me examples of mutable and immutable objects?

Sure! A list is mutable because you can add or remove items. A string is immutable; once created, you can't change its content.

How does this affect performance in Python?

Mutable objects can be more efficient for certain operations since they can be modified in place, while immutable objects may require creating new instances.

Are there any scenarios where I should prefer one over the other?

Yes, prefer mutable objects when you need to change data frequently. Use immutable objects for fixed data to ensure safety and predictability.
