Data Structures in Python

In these tutorials, you’ll learn about built-in data structures in Python. Python comes with a variety of versatile data structures in the core language, as well as in its large standard library.

You’ll also learn how you can implement abstract data structures, such as stacks, queues, hash tables, etc. in Python.
