You can remove validate. You didn't use it

Hey there! 👋 Your code is really well-structured and you're on the right track! However, there are a few improvements that need to be made before it can be approved. Specifically, don't forget to call the validate method in the SlideLimitationValidator class and consider using the @abstractmethod decorator for any abstract methods. Also, remember to add descriptive error messages when raising exceptions, this will make debugging easier in the future. Keep up the good work! 🚀

It's a good practice to provide a descriptive error message when raising an exception. This will help to debug the code if something goes wrong.

The validate method in the SlideLimitationValidator class is not implemented. It's an abstract base class, so it's okay to have a method without an implementation, but it should be decorated with the @abstractmethod decorator to indicate that it's an abstract method and to prevent the creation of an instance of the base class.

Here you're creating an instance of the SlideLimitationValidator class (or its subclass), but you're not calling the validate method. It seems that the validate method should be called here to check if a visitor can access the slide.

Great job on your code so far! 👍 However, there are a few changes that need to be made. The logic within the Slide class and the SlideLimitationValidator class needs to be revised. Currently, the SlideLimitationValidator class is acting more like a data holder than a validator. I would recommend adding a validation method to this class and using it in the Slide class. Keep up the good work! 😊

The SlideLimitationValidator class is a bit confusing. It seems like it should be a class that validates the limitations for a slide. But in its current form, it's more like a data holder than a validator. You should consider adding a validation method in this class and use it in the Slide class.

The can_access method in the Slide class is not working as expected. It tries to create a new instance of SlideLimitationValidator (or its child classes) with visitor's parameters. But these classes don't validate anything during the initialization. I would suggest you to add a validation method in the SlideLimitationValidator class and call this method here.

The IntegerRange class is well implemented. It might be useful to add a docstring to describe its purpose and how it works for future reference.

Your code is generally good, but there are a few issues that need to be addressed. The Slide class logic needs to be corrected and the SlideLimitationValidator class needs to actually perform validation. Despite these issues, I am approving this pull request to encourage you to continue learning and improving. Please review the comments and improve your code accordingly. Keep up the good work! 💪👍🚀

The SlideLimitationValidator class doesn't actually validate anything. It should have a method that takes a Visitor instance as a parameter and checks if the visitor meets the age, weight, and height restrictions.

The can_access method is not using the SlideLimitationValidator correctly. You are trying to instantiate the SlideLimitationValidator with the visitor's age, weight, and height, but the SlideLimitationValidator doesn't actually do anything with those parameters. Instead, you should be calling a method on the SlideLimitationValidator instance that checks if the visitor meets the restrictions.
