Sourcery refactoring suggestions

[Remi-Gau]

Sourcery made a bunch of refactoring suggestions on my fork.

You may want to have a look as some of them seem to make some nested conditionals quite a bit simpler.

Hi @Remi-Gau,
Thank you for pointing out the refactoring suggestions made by Sourcery on my fork. I've taken a look and agree that they could significantly simplify some of the nested conditionals. I appreciate your proactive approach in highlighting this.

I plan to implement these suggestions in the upcoming update, which is scheduled for the next 2 to 3 weeks. Your input is invaluable, and I'm grateful for your contribution to enhancing the project's quality.

Thanks once again for your support and suggestions!
