Python Data Structures

Udemy Course

This repository holds all the supporting files for my Python Data Structures A to Z course, including all the presentations in PDF format, and all the code in Jupyter Notebooks. These resources are available under the MIT license.

This course covers the following topics:
Section 1: Intro, Python native data structures, String, List, Tuple, Set, Dictionary.
Section 2: Stacks, Queues and Heaps.
Section 3: Linked Lists, Circular Linked Lists, Doubly Linked Lists.
Section 4: Binary Search Trees.
Section 5: Graphs.

Each section (2-5) explains how the data structure works, key methods, use cases, and walks through how to implement it in Python 3 code.

udemy_data_structures's Issues

Typos in Section_2/Stacks, Queues & Heaps.ipynb

First off, thank you very much for this great Udemy course on data structure! It's very helpful and easy to understand :)

Looking at your source code, I saw 2 typos in Section_2/Stacks, Queues & Heaps.ipynb
inside the sample code for Python Single-ended Queue Wrapper Class using Deque

def dequeue(self, item): should be def dequeue(self): as we only dequeue the first element of the queue (copy past from enqueue?)

inside the peek(self) method, queue.appendleft(ret_val) should be self.queue.appendleft(ret_val) as queue is a property of the class
