Any good algorithm book will describe the algorithms in abstract terms, and not just in one particular language. Because after all, you can implement them in any language. I would recommend "Introduction to Algorithms" by CLRS (Cormen, Leierson, Rivest, Stein). The algorithms are described in pseudocode, not in any particular programming language. For example, their insertion sort is "implemented" as follows: for i = 2 to n key = A[i] // insert A[i] into the sorted subarry A[1:i - 1] j = i - 1 while j > 0 and A[j] > key A[j + 1] = A[j] j = j - 1 A[j + 1] = key You might notice that this already looks close to Python (and that their array indices are 1-based). IIRC Guido was inspired by how pseudocode looks (which is not standardized, just an ad hoc way to describe algorithms in a language neutral way); that's why there's the "Python is runnable pseudocode" memes, and stuff like this . Another popular book is "Algorithms" by Robert Sedgewick; I've never read it, but I assume the algorithms are also described in pseudocode. I've found a github repo where people implement the algorithms in Python. Of course there's also the holy bible TAOCP by Knuth, but that's more a reference for experienced people, as it is incredibly information dense and mathematical. Knuth himself said that "2 pages in my book is somebody's entire career work". More on reddit.com

You are going to end up with a load of resources chucked at you. So ill make a start. Online course (free) Data Structures and Algorithms in Python: https://jovian.com/learn/data-structures-and-algorithms-in-python A book i refer to Introduction to Algorithms: https://mitpress.mit.edu/books/introduction-algorithms by Thomas H. Cormen, Charles E. Leiserson, Ronald L. Rivest, and Clifford Stein Its pricey but im sure you can find a free edition (or ask someone 😉 😏) Start with the basics. Don't try to learn everything at once. Start with the most common data structures and algorithms, and then gradually build your knowledge. I hope this helps! More on reddit.com

Data Structures and Algorithms are language-agnostic. I say that because I just saw a comment asking what programming language you use. Really though, if you're a book person like, CLRS is a good one to look into. Though beware, it's very debatable on whether or not it truly is an "introduction" book. Also, the CLRS book is math-heavy.

If that's not really up your speed, I suggest looking at The Algorithm Design Manual by Skiena. This was the book I used before diving into the CLRS.

If that's also not your speed, I've heard great reviews on the Algorithms Illustrated series by Tim Roughgarden.

For me, personally, CLRS and The Algorithm Design Manual is enough. And now, I'm on my second round of reading through CLRS and trying to understand all the proofs.

Also, last thing, I don't think there really is a "best book" to learn this stuff. It depends on a lot of things -- you just kinda need to try out many books and resources until you find the right one for you.

Good luck!
