We can use unique in the levels argument of factor as unique returns the unique values from the first occurrence of that element, thus it maintains the same order of occurrence as in the original data

When should one prefer OOP over procedural?

Asked 2021-Jun-15 at 06:30

I am venturing into python and wondering what one should look for to make a choice whether to use Object Oriented Programming paradigm or to remain on procedural paradigm. I developed a small program that looks for duplicate media files in two hard drives and delete the duplicates ones in the send drive. Would it best leaving the program as it is or try out the OOP. If yes how best can I convert it to OOP? Disclaimer: Am still a beginner in python so the code may not be in the right shape as required. Sorry for verbosity.

It depends whether you want to enhance the project from time to time then oops is better for ease of maintainability and for larger projects but if you don't want to extend it then using procedural paradigm approach is just fine , while using oops also you use it in class methods .Oops makes more sense when you try to simulate real world environment or something related to real life objects and phenomenon , algorithms are also mostly implemented using procedural paradigm approach , for me procedural paradigm approach works fine untill code reaches 150 lines of code

Inno Setup Music Glitches when exiting

Asked 2021-Jun-14 at 07:52

I've used Martin Prikryl's code for my Inno Setup project. This is the link to his code:

How to make Stop and Pause/Resume/Play music buttons in Inno Setup

I used it with some tweaks on it but the problem is that the music glitches when I finish it.

For example, if the music is working while installing something and when I finally finish the setup, I still hear the glitched Audio for about 3 seconds! It's very annoying!

I think the problem is that we need to unload Music dll's before the installer finishes, as we do with the skin.

I hope you understood my situation and thanks in advance!

This is my Full code (it's not well-arranged sorry) :

If you want to stop the music, when the installer is closing, just use the same code you already have in StopButtonClick from DeinitializeSetup:

Answered 2021-Jun-13 at 10:58

You should be using:

MyRange3.FormatConditions(2).Interior.Color = RGB(255, 255, 0)

because for the range specified i.e. O4:P30 it is second rule and it gives you error because rule number 3 does not exist!

The problem with your code is in the else clause, where you set split to an int. Indeed, you then try to call split[1] right after, thus getting an error. A solution to this problem is to duplicate the splits.update instruction and modify it to work with an int, as described below:
