What are some examples of mutable types in Python?

In Python, mutable types include lists, dictionaries, and sets. They can be changed after creation.

Can you give me an example of how to modify a list?

Sure! You can modify a list using methods like append(), remove(), or by indexing. For example:

my_list = [1, 2, 3]
my_list.append(4)  # Now my_list is [1, 2, 3, 4]

What about dictionaries? How can I change a value?

You can change a value in a dictionary by using its key. For example:

d = {'a': 1, 'b': 2}
d['a'] = 3  # Now d is {'a': 3, 'b': 2}

Are there any performance considerations with mutable types?

Yes, mutable types can lead to unintended side effects if shared across functions. It's important to manage them carefully.
