What you'll learn

This course covers the essential theory of algorithms and data structures. It allows you to see how various real-life algorithms work and to implement them yourself with Python. You will learn to perform a basic time complexity analysis and choose the most efficient algorithm. What’s even more important, you will enhance your algorithmic thinking, which is a crucial skill for programmers and developers.

While progressing through this course, you will:

implement and compare classic data structures: arrays, stacks, and queues;
practice several searching and sorting algorithms (bubble sort, merge sort, and insertion sort);
find out more about hashing and hash functions;
work with weighted graphs and trees and try several graph algorithms, such as Prim's algorithm and Kruskal's algorithm;
implement your own PageRank algorithm, the famous ranking algorithm created by Google;
learn more about Python functions sort() and find() under the hood.

Having completed this course, you will have a better understanding of how real algorithms work. That might be useful both for job interviews and for making your own programs run smoothly.

Learn by doing

# 1

Apply knowledge into practice

You already know the theory. Now it's time to code like you do at work—in a professional IDE, with real project constraints, solving problems that actually matter. Welcome to software engineering as it should be.

# 2

Navigate complexity with surgical precision

Most developers waste months learning random concepts without seeing how they connect. Our interactive Knowledge Map fixes this. It shows exactly how every programming concept relates to others, helping you build a structured mental model of coding.

# 3

Copy the best. Then improve.

Here's what top engineers do that others don't: they study other people's code obsessively. When you get stuck on Hyperskill, you can explore solutions published by other developers. See their exact code. Understand their approach. Learn their tricks.

# 4

Code review that actually makes you better

We stripped code review down to what actually matters: does your solution work? Have you handled the edge cases? Is there a cleaner way to write this? Hyperskill acts like a competent reviewer who actually tests your code. Not genius-level analysis, not architecture debates — just solid feedback on making your code better.

Elevate your engineering mastery through real-world challenges

Master advanced engineering concepts through ambitious projects. Each project deepens your expertise and transforms you from an experienced engineer into an exceptional one.

Password Checker

In ancient times, the concept of passwords existed, and they are still widely used today. Passwords are essential for online security, and using the internet without them is nearly impossible. To ensure your safety, platforms like Google recommend strong, auto-generated passwords that are difficult to remember without password managers. It would be worthwhile to develop a tool that checks how often your commonly used passwords have been compromised, as this can help you assess the strength of your passwords.

Smart Calculator (Python)

Calculators are a very helpful tool that we all use on a regular basis. Why not create one yourself and make it really special? In this project, you will write a calculator that not only adds, subtracts, and multiplies, but is also smart enough to remember your previous calculations.

Graduate

Google Search Algorithm with Python

We all use Google. How does Google manage to return a relevant set of web pages for your search in a blink of an eye? In this project, you will have a chance to implement your own ranking algorithm for web pages based on the technology they use in Google – PageRank. You will practice concepts frequently tested in technical interviews at top tech companies.

I feel like there are a lot of unneeded topics and not enough of the really needed ones. But overall, the projects are pretty good and I enjoyed this track

I didn't really choose this track specifically and just finished it along the way.However, this track has some good projects to sharpen and practice your thinking skills with a good number of well-known algorithms.
