You learned all about linked lists in this course. Like most other data structures, linked lists can be tricky when you’re first learning about them, but with enough practice, you’ll be able to implement them with ease.

In this course, you learned about:

What linked lists are and when you should use them
How to use collections.deque to implement queues and stacks
How to implement your own linked list and node classes, plus relevant methods
What the other types of linked lists are and what they can be used for

Congratulations, you made it to the end of the course! What’s your #1 takeaway or favorite thing you learned? How are you going to put your newfound skills to use? Leave a comment in the discussion section and let us know.

00:00 You learned all about linked lists in this course. To recap, you learned: what linked lists are and when you should use them; how do you use collections.deque to quickly implement stacks and queues; how to implement your own linked list and node classes, plus relevant methods; and finally, what other types of linked lists exist and what they can be used for. Like most other data structures, linked lists can be tricky when you’re first learning about them, but with enough practice, you’ll be able to implement them with ease.

00:37 You’ll also learn to recognize scenarios that could use the linked list or its derivatives, like the stack and the queue. If you want to learn more, I’ll include some helpful links down in the video notes below.

00:51 Thanks for joining me on this journey through linked lists. I’m Austin Cepalia with realpython.com. Happy coding!

I’ll need some time to digest the course but it was very well explained and presented. Thanks!
