How do I implement nested data structures in Python?

You can use lists and dictionaries to create nested data structures. For example, a list of dictionaries can represent a collection of items.

Can you give me an example of a nested dictionary?

Sure! Here's an example:

nested_dict = {
    'person1': {'name': 'Alice', 'age': 30},
    'person2': {'name': 'Bob', 'age': 25}
}

How would I access Bob's age in that structure?

You can access it using:

nested_dict['person2']['age']

This will return 25.

What if I want to add another person to the dictionary?

You can add another entry like this:

nested_dict['person3'] = {'name': 'Charlie', 'age': 28}
