What are some examples of mutable data in programming?

Mutable data refers to data that can be changed after its creation. Examples include lists and dictionaries in Python.

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

Sure! In Python, you can modify a list using methods like append(), remove(), or by accessing an index directly. For example, my_list.append(4) adds 4 to the end of the list.

What about dictionaries? How can I change a value?

You can change a value in a dictionary by using its key. For example, if you have my_dict = {'a': 1}, you can change the value of 'a' by doing my_dict['a'] = 2.

Are there any downsides to using mutable data?

Yes, mutable data can lead to unintended side effects, especially in functions where the original data can be altered. It's important to manage it carefully.
