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. Examples of mutable types include lists and dictionaries, whereas strings and tuples are immutable.

Can you give me examples of mutable and immutable types?

Sure! A list is mutable because you can add or remove elements from it. A string is immutable; once created, you cannot change its content.

Why is it important to know the difference?

Understanding the difference helps in optimizing performance and avoiding unintended side effects in your code.

How does this affect memory management in Python?

Mutable objects can be modified in place, which can save memory, while immutable objects require new memory allocation for changes.
