What is mutability in Python objects?

Mutability refers to the ability of an object to be changed after it is created. In Python, some objects are mutable, like lists and dictionaries, while others are immutable, like tuples and strings.

Can you give me an example of a mutable object?

Sure! A list is a mutable object. You can add, remove, or change its elements after it has been created. For example, you can do my_list = [1, 2, 3] and then my_list.append(4) to add an element.

What about immutable objects? Can you explain that?

Absolutely! An example of an immutable object is a tuple. Once you create a tuple, you cannot change its elements. For instance, my_tuple = (1, 2, 3) cannot be modified.

Why is it important to understand mutability?

Understanding mutability is crucial for managing memory and performance in Python. It helps you avoid unintended side effects when passing objects around in your code.
