How can I use nested structures in programming?

Nested structures allow you to create complex data types by combining simpler ones. For example, you can have a list of dictionaries in Python.

Can you give me an example of a nested structure in Python?

Sure! Here's a simple example: students = [{'name': 'Alice', 'age': 20}, {'name': 'Bob', 'age': 22}]. This is a list of dictionaries.

How do I access the name of the first student?

You can access it using students[0]['name'], which will return 'Alice'.

What if I want to add another student to the list?

You can append a new dictionary to the list like this: students.append({'name': 'Charlie', 'age': 21}).
