How do I use nested collections in Python?

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

Can you give me an example of a nested dictionary?

Sure! Here's an example:

students = {
    'student1': {'name': 'Alice', 'age': 20},
    'student2': {'name': 'Bob', 'age': 22}
}

This creates a dictionary where each student has their own dictionary with details.

How can I access a specific student's name?

You can access a student's name like this:

print(students['student1']['name'])  # Output: Alice

What if I want to add another student?

You can add a new student by simply assigning a new key-value pair:

students['student3'] = {'name': 'Charlie', 'age': 21}
