Watch: Data Structures, Stacks, and Queues in Python

Image credit: Author

Data structures organize data in ways that make it efficient for their data to be accessed in particular ways by placing constraints on how the data is accessed. Data structures may also place constraints on the data itself, such as a uniqueness constraint on items in a set — I talk about that in Set Basics in Python.

In this video, I talk broadly about data structures, briefly about stacks, and at length about queues and the deque Python module for easily creating and using queues.
