Data structures and algorithms are among the most fundamental concepts of Computer Science. Whether it’s real-world problems you’re trying to solve or the typical coding question asked in an interview, almost every problem requires you to demonstrate a deep understanding of data structures and algorithms. 

This course is a detailed review of some of the most common data structures and algorithms that you’ll see in interviews and your everyday work. With implementation details, thorough explanations, and hands-on coding exercises, you’ll quickly gain the confidence you need to solve any problem, no matter the situation.

Data Structures and Algorithms in Python

In this lesson, we introduce the doubly linked list data structure and code up an implementation of this data structure in Python. 

After that, we look at how to append (add elements to the back of the doubly linked list) and prepend (add elements to the front of the doubly linked list). 

Finally, we will write a print method to verify that the append and prepend methods work as expected. 

In this lesson, you will learn how to implement doubly linked lists and insert elements in it using Python.
