Glad you found the video useful! :) I'd like to create more videos this year, so please stay tuned.

In the Wagner-Fisher algorithm, when computing d[i, j] you take minimum of the neighbors d[i-1, j], d[i, j-1], d[i-1, j-1] with cost of the operation added to each. Usually all the costs (weights) are set to 1, except for the case of d[i-1, j-1] when a[i-1] == b[j-1] (which is a match, so it should not add to the distance).

Thanks! It's Jupyter Notebook with github.com/dunovank/jupyter-themes and some custom CSS styles on top using github.com/openstyles/stylus

@@BigPython Thank you very much!

@@BigPython I played with the styles a little bit, and figured, that you were using the grade3 style. However my understanding of the openstyles, that is has to applied to the browser itself. Is that correct? Do you mind sharing your style?

@@lammelmiklos3765 Yes, it's applied at the browser level. I've added my current CSS to the git repo, feel free to have a look :) github.com/tkarabela/bigpython/blob/master/jupyter-grade3-bigpython.css

Thanks! Yeah, multiple cursors are pretty cool, I still remember when I first saw them used by our college prof... I was like "what just happened" :D

If you mean "try: ... except Exception as e: match e: ..." then I suppose it should, haven't tried it. The try/except statement already works kind of like pattern matching, I don't remember wanting more from it :)

Thank you! :)

Thank you! I used to do private tutoring while I studied at university, so I guess I miss explaining this stuff :D Teaching is a good way of learning, nothing quite makes you understand a subject like having to break it down for someone else. Your videos have a nice easy-to-understand presentation and great visuals, I'd love to see your take on some more advanced topics! I'm sure you'll get there in time :)

Thanks, I'm glad it was helpful :)

Yeah, all the fancy languages seem to have something like that ^^

Yeah, it looks very nice, esp. in combination with dataclasses :)

@@BigPython looks great. thank you, will try this out.

Glad it was useful! I have something in the works on Levenshtein automata and Tries, that video is coming :)

Sure! The Entities don't really need to be dataclasses, it just saves a bit of code for __init__ and printing to console. The Messages on the other hand fit dataclasses well I think (they don't have any logic, just contain data). However, there are some strange cases like SpawnFoodMessage which doesn't have any attributes (which doesn't make much sense from OOP point of view). The Message hierarchy is basically an ADT (algebraic data type) like you would have in Haskell or Rust - think enum, but each variant can have its own dataclass and not just unique label. Alternative approach would be to have just one Message class, which would have two attributes: message type (integer ID, or better - enum) and message contents (dict). I believe this is what PyGame does for its events. This makes it easier to implement, but the message structure is less clear - with the strongly typed ADT approach, it's just not possible to create some kinds of invalid messages (EntityCollisionMessage without two entities, etc.), and possible messages are quite obvious from the definitions. When you just say "Message is an ID with a dict", then you don't get these typing advantages.

Thank you! :)

Thanks!

Thanks! I hope you'll find it useful :)

Match is actually much more powerful than switch

Thanks for the kind words! Well, I've started it just a few days ago, let's see where it goes :)

It's regular Jupyter with Jupyter-themes ( github.com/dunovank/jupyter-themes ), I believe it's the "grade3" skin. It's as simple as "pip install jupyterthemes" and "!jt -t grade3". I have it in the last cell in the notebook: github.com/tkarabela/bigpython/blob/master/002--python-3-10-pattern-matching/structural-pattern-matching.ipynb

Glad you found it useful :) Thanks for stopping by!
