Open Trivia Database for PyQt5 GUI App - PART 2

Your teaching is easy to understand loved the way you explained;-);-)

[@PythonSimplified]

Thank you so much, I'm glad you liked it! 😃

[@LuisSolis]

Great tutorial, answering the question I think the detail is in the random function, the random is good but could repeat the same question. I expect that's the answer xD.

[@PythonSimplified]

YES YES YES! You got it! 😃😃😃 Virtual tap on the shoulder coming right at ya Luis! I'm telepathically sending it to you hahaha 🤣 And now the second part of the riddle - how would you solve it? 😉

[@LuisSolis]

@@PythonSimplified Great great wooo I'm the winner hahaha Thank you for your telepathically help, haha, Maybe I make a global list of indexes and later create a random list of indexes and after getting these indexes with the random erase the value that's returned.

[@PythonSimplified]

@@LuisSolis hahaha that's awesome! It's a great way to solve it!! 😃 I would probably do something similar - I'll also track the randomly selected indices with a global list, I would just use a while loop to check if idx is not in list_of_indices before calling preload_data() 😉 If the index already appears in the list - I would keep generating new random numbers inside the loop until we get a brand new index that wasn't used before 🤓 Thanks again for the solution to this riddle Luis! So far you're the only one who figure it out! 🤩

[@LuisSolis]

​@@PythonSimplified Thank you so much Sensei. I will wait for your new tutorial, I'm so new to programming in Python.

@@PythonSimplified shuffle 50 numbers in the list: parameters["index"].append(random.sample(range(50), 50)) for correct answer just pop value and do not append: parameters["index"].pop() # parameters["index"].append(random.randint(0,49))

[@CurrentElectrical]

So looking forward to this. :D

[@PythonSimplified]

Yey! super glad to hear that, thank you!! 😃

[@flioink]

Edit: made it by making a function that generated a list of unique integers, then added a call to that function in the start_game function(clearing it beforehand). Then in the is_correct function I give - parameters["index"].append(inset[0]) where "inset" is the list of unique ints. Next line is inset.pop(0) to remove the index we just used so the next becomes first and so on. Seems to do the trick without an issue so far.

[@oreh350]

Thank you! Everything works! I think the issue is we can have some questions repeated and, frankly speaking, I don't know how to solve this problem. I guess we need to create a for loop checking if a new question matches of any previous ones and start the loop again till the problem is gone.

[@RazerJones]

Hey man, that's a feature. I think the bug is the centering of the score inside the green circle.

So the compiler read it done pass perfect. Next one is convert .py to .exe files to hope will working on auto-py-to-exe. Then you can do “Inno Setup Setup” go to website “innosetup-6.2.0.exe” you can install it to read it step by step that is fastest install easy wizard Application.

Hey not specifically about this video but noticed the curved screen .. would you recommend that for programming... currently I have 3 screens and really interested in how the curve affects your coding (if at all) .. cheers

[@PythonSimplified]

Hey Robert! 😃 I really like my curved screen, especially since it's 5k and 240hz (ultra wide and very very very curved). It's the Samsung G9 and from what I understand - it's extra curved to ensure that every point on the screen is in the same distance from the eye. With that said, I don't know if you can see any benefit in terms of coding. I can definitely guarantee it would make you feel like you're coding inside a spaceship command centre, but I don't find it's particularly beneficial in terms of programming... However - it's perfect for gaming (especially Forza and Flight Simulator, it mimics a real car/plane interface! you feel like you're inside the game) and I find that it's great for video editing. The curve makes everything look futuristic and fancy, but if your 3 screens already have 4k & 240hz features - I don't believe it's worth replacing them with the G9. Only if their specs are not near that, I would recommend doing so - your eyes will thank you! 😁

[@toddbirtcher]

I enjoyed learning with this video, and then I was curious what it would take to upgrade to PyQt6. I only had to change PyQt5 to PyQt6, pip install pyqt6, and change AlignCenter to AlignmentFlag.AlignCenter, change PointingHandCursor to CursorShape.PointingHandCursor. Then, I could run the game with no errors. I noticed that the window was a little larger than when it ran under PyQt5. I was doing this only to learn something and not sure why the window is larger.

[@aaron.1985]

This is so cool.

[@J-S_93]

Just wondering why you never used auto-py-to-exe to release a completed exe version of the Trivia app on the GitHub page? It would be nice to try the completed exe app first before installing the dependencies used to run the py files standalone, as the programmer py and functions py won't function, lol; at least not w/o their requirements/dependencies being installed first - If it was in executable form, I assume it would contain within, everything it needs to run standalone, on a system that doesn't have any of the things required to make it work installed

[@avazart614]

Лично мне немного режет глаза код написанный "простыней" без разбиения на файлы без использования *.ui и дизайнера форм, единой точки входа. Кроме того в данном конкретном коде не хватает обработки ошибок на случай недоступности сервера, отсутствия интернета, ответа в виде некорректного json от сервера. Все же стоит разместить загрузку с сервера где-то в конструкторе виджета или может в таймере и обязательно обрабатывать исключения и выводить их пользователю в виде QMessageBox. Обычно вместо urllib люди используют стороннюю requests она более удобная. Так как это Qt можно было бы вообще использовать QNetworkAccessManager который асинхронный.

Splitting Layout from Code is one of the important rules and this is not only for QT true. So maybe you show the same project again, but then with QT-Designer.

what is the best Library Tkinter or PyQt5 ??

[@avazart614]

PyQt5

[@PythonSimplified]

For personal use I absolutely agree with Avazart! PyQt5 is much more intuitive, user-friendly, stylish, and interactive. Also many people find the QT Designer useful. I haven't used it in this video, but I got many comments wondering how come I didn't (ehem ehem Avazart 😂) For commercial use, people prefer Tkinter because it has better licensing options, but the widgets are very old school, the commands are not as intuitive and in general - it lacks a lot of styling options. It was a real nightmare developing my advanced PDF Extract app. I recommend reading what miko007 wrote in this community post: kzbin.infoUgx7FTaTtzd_kf5k39t4AaABCQ I specifically asked him about the difference between Tkinter and PyQt5 and he had lots of interesting things to say 😃 You may find it very useful for solving your dilemma 😉

[@avazart614]

@@PythonSimplified The devil is in the details. Tkinter contains a ttk sub-library with more stylish windows PySide2 is a complete PyQt5 clone but with a different license. Among other things, there is the Kivy library. IMHO, Qt is better than Tkinter due to the presence of the Qt Designer and more understandable layers. More importantly, Qt has its own means for synchronizing threads, which allows you to build interactive applications without freezing. Qt support MVC pattern what is useful when working with databases. But Qt is library with heavyweight binary files. More options - more in weight. Qt contains libraries not only for GUI: for working with the network, charts, databases, serial port, etc. So I would argue with @ miko007

It wasn't until I started working with P5.Js and building Javascript web apps that I fully understood the concept of OOP and why classes are better to use than regular functions.
