I Tried 20+ Python DSA Courses with LeetCode Exercises on Udemy: Here Are My Top 5 Recommendations for 2026
My favorite Udemy courses to learn Data structures and algorithms for interviews on Udemy
If you want to crack coding interviews at companies like Google, Amazon, Meta, Microsoft, or even fast-growing startups, then mastering Data Structures and Algorithms (DSA) is still one of the highest ROI skills you can invest in.
Along with System Design, DSA is the most important skills for tech interviews, even in this AI era. While things are changing but interviewer still want you to solve coding problems without using AI on interview and you can only do that if you have good knowledge of DSA.
Over the last few years, I have tried many resources for coding interview prep like AlgoMonster, Exponent, ByteByteGo, Educative, or DesignGuru but for learning basics, I have always used Udemy courses.
In last 2 years, I’ve reviewed and explored more than 20 Python DSA courses on Udemy while helping developers prepare for coding interviews.
Some courses focus heavily on theory, some are packed with coding exercises, while others do a great job teaching LeetCode-style problem-solving patterns.
The good news is that you don’t need dozens of courses.
If I had to start again in 2026, these are the five Python DSA courses I would recommend the most.
Why Learn DSA with Python?
Python has become one of the most popular programming languages for coding interviews because:
- Clean and concise syntax
- Faster implementation during interviews
- Huge collection of built-in data structures
- Widely used by FAANG candidates
- Excellent support for competitive programming and LeetCode
If your goal is interview preparation, learning DSA using Python is often the fastest route.
It’s also slightly easier to solve complex DSA problems on Python than solving them on Java or C++.
Though, once you learn DSA basics, I highly recommend you to learn about coding Patterns like two pointers, prefix sum, fast and slow pointers etc. They will help you to solve DSA problems quickly, if you need resource, AlgoMonster is my favorite place to master coding patterns.
5 Best Udemy Courses to learn DSA with Python for Interviews
Without any further ado, here are the top Udemy courses you can join to learn DSA with Python
1. Complete Python With DSA Bootcamp + LEETCODE Exercises
Best Overall Course for Beginners and Interview Preparation
This is probably the most complete Python + DSA package currently available on Udemy.
What I particularly like is that it doesn’t assume you already know Python. The course gradually takes you from Python fundamentals to advanced data structures and then into LeetCode-style interview questions.
What you’ll learn
- Python fundamentals
- Arrays and Strings
- Linked Lists
- Stacks and Queues
- Trees and Graphs
- Recursion
- Dynamic Programming
- LeetCode problem solving
Why I recommend it
If you’re starting from scratch and want a single course that covers Python and DSA together, this is the one I’d choose.

2. Python Data Structures & Algorithms + LEETCODE Exercises
This course strikes an excellent balance between theoretical understanding and practical coding exercises.
Unlike many DSA courses that simply explain concepts, this one provides extensive coding practice and LeetCode-style exercises after each topic.
What you’ll learn
- Time and Space Complexity
- Arrays
- Hash Tables
- Trees
- Graph Algorithms
- Sorting Algorithms
- Searching Algorithms
- LeetCode Interview Problems
Why I recommend it
The structured progression makes it ideal for developers preparing for coding interviews over a 2–3 month period.

3. Master the Coding Interview: Data Structures + Algorithms
This has been one of the most popular coding interview courses on Udemy for years — and for good reason.
The instructor does an excellent job explaining the intuition behind algorithms instead of simply showing solutions.
What you’ll learn
- Big-O Analysis
- Arrays
- Hash Tables
- Trees
- Graphs
- Recursion
- Dynamic Programming
- Interview Strategies
Why I recommend it
If your primary goal is passing coding interviews rather than becoming an academic algorithms expert, this course delivers tremendous value.

4. The Complete Data Structures and Algorithms Course in Python
This course focuses heavily on building a strong DSA foundation.
The explanations are detailed, and every major data structure is implemented from scratch, which helps deepen your understanding.
What you’ll learn
- Arrays
- Linked Lists
- Stacks
- Queues
- Trees
- Graphs
- Searching Algorithms
- Sorting Algorithms
Why I recommend it
Great for developers who want to truly understand how data structures work internally rather than memorizing interview patterns.

5. Data Structures and Algorithms: In-Depth DSA using Python
If you’re looking for a deeper dive into algorithms and data structures, this course is worth considering.
It covers many advanced concepts often skipped by beginner-friendly courses.
What you’ll learn
- Recursion
- Trees
- Graphs
- Greedy Algorithms
- Dynamic Programming
- Searching Techniques
- Sorting Techniques
- Complexity Analysis
Why I recommend it
Excellent for developers aiming for senior-level interviews or competitive programming challenges.

My Recommended Learning Path
If I were preparing for coding interviews in 2026, here’s what I would do:
- Start with Complete Python With DSA Bootcamp + LEETCODE Exercises
- Solve 100–150 LeetCode problems
- Take Master the Coding Interview
- Practice medium-level interview questions daily
- Participate in mock interviews
This combination is more than enough to prepare for most software engineering interviews.
Final Thoughts
The biggest mistake developers make is jumping directly into LeetCode without first understanding the underlying data structures and algorithms.
A good DSA course can save hundreds of hours of frustration and dramatically improve your interview performance.
If you’re a beginner, my top recommendation is Complete Python With DSA Bootcamp + LEETCODE Exercises because it combines Python fundamentals, DSA concepts, and LeetCode practice in a single package.
If you’re already comfortable with Python, Master the Coding Interview: Data Structures + Algorithms remains one of the best interview-prep courses available on Udemy.

Remember: Consistency beats intensity.
Spend 60–90 minutes daily solving problems, and within a few months you’ll be significantly stronger than most candidates entering coding interviews.
I also recommend you to learn about coding Patterns like two pointers, prefix sum, fast and slow pointers etc. They will help you to solve DSA problems quickly, if you need resource, AlgoMonster is my favorite place to master coding patterns.
