Hearted Youtube comments on Indently (@Indently) channel.

  1. I read this title as Python 5 and thought I woke from a coma

  2. after hour and hours and trainings, someone explains in 3 seconds the role of if _name_ = ''__main__' ,omg, thx a lot !

  4. Your post was created 2 years ago, but it's still helping newcomers.

  5. Its good that you showed working of the memoization, but there are some inbuilt decorators for this exact same process, we can use cache or lru_cache from functools library. So that we don't need to write the memoization function every time.

  6. Another important thing with main() is the scope. Code run in "if name main" uses global scope and can/will pollute it. Running code in main has the function's scope :)

  7. Now I have to type an extra dot in my imports, with everything going on in the world, I have to deal with too!?

  9. This is the first time I have seen someone specify datatype for variables in python, and I honestly loved it. Great tips btw.

  10. Very useful for closing out db connections and for "clients" to send hearbeat "lost connection" status

  11. For all of you that actually want to make a discord bot, this is the only one i could find that actually helps :)

  12. as a c/c++ enjoyer i must say that it warms my heart that specifying the return type not only is a thing, but a recommended practice

  13. I learned about using finally for releasing locks in concurrent programming. My professor said that if you don’t release the lock in a finally, what can happen is like going into the bathroom, locking the door, and then jumping out the window. Defensive programming for the win!

  14. You went to a very dangerous territory here... Using pickle to store state of objects in long term has a lot more caveats than just "don't load random stuff from the internet'. 1. Pickle is Python only format. You can't read it from anything else or look at stored data. Even within python there are several versions of pickle and you can't load files stored in newest pickle format on older versions of python. (Last change happened at python 3.8) 2. More importantly, pickle depends deeply on the structure of your code, modules and classes. You can only safely unpickle objects that were stored with the same code structure. Programs tends to change over time. Storage formats change less often and it's easier to consider what to do with old data. Add new attribute to your class or rename one. If you attempt to load pickle file stored in previous version, an object will be restored with attributes as they were in a previous version and they probably won't match the changes you made. Rename the class or put it into different module — and loading will fail. 3. There is a reason why saving into json takes a lot of repeating code: you actually need to say explicitly, what are you planning to store and what name should be attached to it. Your classes could contain some data that is deduced on the fly and there is no use in storing and loading them. And without additional code pickle would just store everything from object (well, technically not everything, there are some exceptions by default). You could specify what to pickle and what not to pickle, but then we return to the same state as before which is — we need to be explicit about what to store and how. 4. There are proper ways to stay with normal interchangeable formats and not writing too much boilerplate. Projects like pydantic, dataclass-json, dataclass_wizard, dataclass_factory and others allows you to specify mapping between most of formats (like json, yaml, or some dictionary loaded from sql database) and your classes. 5. Main purpose of pickle remains to be short term storage of objects so they could be transferred between parts of the system that you maintain, for example, for interprocess communication or sending tasks to worker farm run by celery. And pickle was never intended for long term storage of the system state like you are implying. To summarise: don't use pickle this way if that's not a one-time task and you are planning to use what you have written two month later, there are better solutions.

  15. With a bare except block, you are also catching KeyboardInterrupt, something you definitely don't want in a console program.

  16. For those of us coming from strongly typed languages, type hinting is a nice little security blanket.

  17. IIFE is used to hide variables within a scope. it executes once, pops off the stack and wipes from memory. its used for naming collision safety.

  18. Geez, it seems like the people in this comment section either don’t know Python, have never programmed anything larger than a todo list, or are being intentionally dense. Nice video.

  19. I feel like the most useful case where you'd use strip() was left out of this video. When used with no parameters, it strips spaces from the beginning and the end of a string. It's used all the time as the first step in sanitizing data from user input. I loved this video regardless though! I did not know about some of these, namely the weird fill ones
    141
  20. Why can't people makes simple videos that work like yours? So gud, thank you maan
    131
  21. THE braces one made my day
    130
  22. One minor point: to make the search case-insensitive, you should really lower the input as well.
    127
  23. I was wondering, Could you make some sort of code review type videos ? I know it probably takes more time but at the same time you could also explain a lot of other stuff, like how to handle big sized projects, how to make code more professional on a larger scale ... This could really be cool I think

  24. FYI. In python, only os._exit() will terminate the python process directly. Since it execute the system call. Other kind of exit() methods will raise a SystemExit and let you catch that.

  26. By the way, a better path formatting option is pathlib. For example, it makes sure the slash is correct.

  27. They've been deprecated since 3.9, but weirdly there are (currently) no concrete plans to actually remove these aliases. Even looking forward as far as 3.16 there's nothing. I think they might be "soft-deprecated" or something, as yeah Pylance doesn't mark them as deprecated either. I forget how I found out initially actually, I remember something flagged it to me, though I still use typing lmao.

  28. I've seen dozens of "python tips" videos like this and learned almost nothing. They went from giving tips everybody knows to outright horrendously bad code. This one is the first where I actually learned something (that you can pass functions as first class objects) and every tip was actually relatively unknown, but still useful and presented in well written code. Compliment!

  29. There's also the successor operator -~ with -~0 = 1, -~1 = 2, ...

  30. I Love when youtubers make clear tutorials! Awesome work! keep it up!
    90
  31. Looks like the style is converging into VSCode

  32. Personally I only use type hints in function definitions because it helps with documentation. Not having to do that for every variable is like half the reason I’m using python in the first place 😅
    90
  33. I've been using python for about 10 years, and f strings extensively, but never knew that last tip! Game changer!

  34. i messed up, i made a recursive function and now i can't stop making pizzas
    85
  35. I had been searching for a proper tutorial on a discord bot using python, but I couldn't find one since every video was outdated , and the documentation also made no sense. Thanks for the great work.
    84
  36. Great video! Btw love HAIRY Potter 😂

  37. To add to this nice video: Memoization isn't just some random word, it is an optimization technique from the broader topic of "dynamic programming", where we try to remember steps of a recursive function. Recursive functions can be assholes and turn otherwise linear-time algorithms into exponential beasts. Dynamic programming is there to counter that, because sometimes it may be easier to reason about the recursive solution.
    81
  38. Thanks, today was my off day and I randomly found this video. First I made this exactly as you taught, then I changed stuff and learned more about python (I'm a JS developer). Best way for a software developer to spend his off day :)

  39. ⁠ @Indently hey Federico! Your point is valid, but i don't think it was clear which is why he was trying to help. There is a clear distinction between camelCase and UpperCamelCase, and although he may not have been aware of this, I believe was just trying to help others not get confused.
    78
  40. i love the way you pronounce “category”, very unique haha

  41. the number inside the brackets does not say how many times that line is executed but it shows the sequence number that lines executed base on them , ie: your next line will show the number 3 , cause it is the 3rd cell that is executed .
    69
  42. This video is choice(['cool', 'amazing', 'random'])
    67
  43. We generally call the name, parameter types, and return type of the function a "signature", not a "title".

  44. Very nice collab! The deprecated decorator was a very much necessary functionality, especially for libraries. Coming from a Java background, not having this decorator in the main Python language surprised me.
    67
  45. With the changes you need to fix client= - Here's the change: client = discord.Client(intents=discord.Intents.default())

  46. So for my bonus homework problem, I changed it to asynchronous to work with a discord bot. I added the ability to have multiple answers in a list and to pick a random answer. I also added an add command that will prompt the user to add a question and answer manually. If the answer is not found, it will create a new entry in the knowledge base. If the answer is found, it will change the string answer to a list and add it, or add to a list if there is one. Thank you so much for this! I just started learning programming a few months ago and the way you explained it helped me out a lot.

  47. Premature optimisation is a particular issue of mine. Probably more when I'm doing C/C++ code than Python, but I still do it.

  48. I am glad that I found this tutorial. I am a 2nd semester student in computer science where I am learning python. While I was searching for something new that I can learn in advance of my class, I found this masterpiece that opened my mind and the way of thinking. I really appreciate your effort and I am gonna suggest my friends to follow this.
    58
  49. Python is such a nice feeling language to interact with, channels like this are so nice for learning all the little features :)
    57
  50. nice!, now I can program my anime waifu bot to send me good morning messages and pictures when I say something nice to it
