What are some examples of nested structures in programming?
Nested structures refer to data structures that contain other data structures. For example, in Python, a list can contain other lists, or a dictionary can contain lists or other dictionaries.
Can you give me a specific example in Python?
Sure! Here's an example: my_list = [[1, 2, 3], [4, 5, 6]]
is a list containing two lists. You can access elements like my_list[0][1]
to get 2
.
What about nested dictionaries?
Absolutely! A nested dictionary example would be: my_dict = {'a': {'b': 1, 'c': 2}, 'd': 3}
. You can access my_dict['a']['b']
to get 1
.
Are there any real-world applications for nested structures?
Yes, nested structures are commonly used in JSON data for APIs, representing complex data like user profiles or product catalogs.
