5 Best Online Courses to Learn Data Structure and Algorithms in Python [2021]

Hello guys, if you want to learn Data structure and Algorithms in the Python Programming language and looking for the best online courses then you have come to the right place. In the past, I have shared a lot of useful resources like free data structure courses, books, and tutorials to learn Data Structure and Algorithms for programmers. I have also shared a lot of Algorithmic interview questions and their solutions in Java, but I have been constantly getting queries about good courses to learn Data Structure and Algorithms in Python. Even though the topics are completely independent of the programming language, Python developers definitely like the courses and books which teach Data Structure and Algorithms in Python.
In my recent post about the best algorithms courses, which include algorithms courses from Java and JavaScript, I did mention a Python course to learn Data Structure but my readers ask for more alternatives.

Some of them also requested free algorithms courses instead of paid ones while others are happy with the good course regardless of whether it's free or paid.

In order to fulfill my promise, I did some more research and bring with me a new list of Data Structure and Algorithms courses in Python which contains both free and paid courses.

Some of the courses like Python for Data Structure is common from my previous list, obviously because it is one of the best course to learn algorithms and data structure in Python. But, the list also contains some new entrants like the Python Data Structure course from Coursera. 

This time, I have focused more on coverage of essential data structure in a fun and interesting way, rather than picking the course which covers a huge number of data structure and algorithms but didn't do justice with that.

Another reason I have included more than a few courses is becuase not everybody connects to the instructor I like. Everybody is different and they should only join the course where they can connect to the instructor, I mean they like his voice, the style of explanation, and the content.

If you join a course where the instructor is both knowledgeable and enthusiastic and also has good teaching skills, you obviously learn more and retain that knowledge for a long time. That's the goal of this article to come up with courses that provide value for both your time and money.

5 Best Data Structure and Algorithms Courses to Learn Python

Without wasting any more of your time, here is the list of best data structure and algorithms courses for Python developers.  You can join a couple of these online courses to learn Data Structures and Algorithms in Python. 

1. Python for Data Structures, Algorithms, and Interviews!

This is the best Udemy course to learn Data Structure and Algorithms with Python on Udemy. This Python data structure course will teach you all the key data structure and algorithms you need for your day-to-day programming task and to crack coding interviews.

Here are the key things you will learn in this course:
  • How to create a great resume
  • How to build impressive LinkedIn and Github profile for recruiters
  • All major Data Structures and Algorithms in Python like an array, lists, dictionaries
  • Mock interviews to crack your next coding interview.
This course is created by none other than Jose Portiall, instructor of the Complete Python 3 Bootcamp course and it Talking about social proof, this course has on average 4.4 ratings from close to 7,892 ratings and more than 51,309 students have already enrolled in this course. 

Overall a great course that systematizes your algorithm & data structure knowledge as well as gives you great exercises to test your skills both soft and hard skills and help you to get success in interviews.

2. Algorithms and Data Structures in Python [Udemy]

This is another hands-on course to learn Data Structure in Python on Udemy. This course provides a practical guide to implement the most up-to-date algorithms from scratch: arrays, linked lists, graph algorithms, and sorting. 

Created by Holczer Balazs is a massive course with more than 160 lectures and more than 14.5 hours of content, this is one of the most comprehensive courses to learn key data structure and algorithm in Python.

The course can be broadly divided into two parts, In the first part, you will learn about basic data structures such as linked lists, stacks, queues, binary search trees, heaps, and some advanced ones such as AVL trees and red-black trees. the second part covers more advanced concepts like graph algorithms such as spanning trees, shortest path algorithms, and graph traversing.

In each chapter Instructor first talks about the theoretical background of each algorithm or data structure, then writes the code step by step in Python. This routine is best for beginners and helps you to learn both theory and practical aspects.

Talking about social proof, the course has on average 4.2 ratings from close to 22000 reviews and more than 14K students have joined this course which speaks a lot about its quality. (2,189 ratings)

3. LeetCode In Python: 50 Algorithms Coding Interview Questions [Udemy]

This is one of the unique courses to learn Python data structure and algorithm on Udemy. This course actually takes LeetCode problems and provide the solution in Python and explain to them which kind of make it useful as you learn about problem-solving, data structures, and algorithms for technical interviews at companies like Google and Amazon.

As the title suggests it provides a solution of 50 hand-picked leetcode problems which include data structure string, array, list, dictionaries, trees, hash tables, graph, stack, queue, etc. You will also learn a lot of useful algorithms like sliding window, backtracking, dynamic programming, and learn some useful problem-solving tips to solve coding problems in real interviews.

On the cons side, the course has some sound issues but the content and style compensate for that. I really like the idea of two videos - explanation and implementation, which makes learning easy and fruitful. Talking about social proof, the course has an average 4.5 rating which is impressive.

4. Data Structures for Coding Interviews in Python [Educative]

Data structures are amongst the most fundamental concepts of Computer Science. The data structure chosen can make or break an entire computer program. Consequently, they are also largely categorized as a vital benchmark of computer science knowledge when it comes to industry interviews. 

This course contains a detailed review of all the common data structures and provides implementation-level details in Python to allow readers to become well equipped. Now with more code solutions, lessons, and illustrations than ever, this is the course for you!

5. Python Data Structures [Coursera]

This is one of the most popular online courses to learn Python Data Structure and more than 561,102 have already enrolled in this course. 

This course is also part of Coursera's most popular the Python for Everybody Specialization and its offered by the University of Michigan. This course is delivered by Charles Russell Severance and it has on average 4.9 rating from more than 50K reviews which is phenomenal.

Here are the main things you will learn in this course
  1. What is the data structure and how they are used?
  2. How to read and write data from files
  3. How to store data as key/value pairs using Python dictionaries
  4. How to accomplish multi-step tasks like sorting or looping using tuples
This course will introduce you to the core data structures of the Python programming language. You will also learn how to use the Python built-in data structures such as lists, dictionaries, and tuples to perform increasingly complex data analysis. This course will cover Chapters 6-10 of the textbook “Python for Everybody” and it is based upon Python 3.
