Fixing AttributeError: How To Properly Use Classes in Python

If you're just starting with programming in Python, you might encounter a common error related to classes that can be a bit confusing. Have you ever seen the message "Unresolved attribute reference" or faced an AttributeError like this one?

This error typically arises when you're trying to access a class attribute without creating an instance of the class first. In this post, we will go through the concept of class instantiation in Python and show you how to fix the error you’re facing.

Understanding the Problem

To better understand the issue, let's take a look at the error message you received:

In your code, you're trying to access question directly from Class, which leads to the error because question is an instance attribute, not a class attribute. This means you need to create an object of Class before accessing its attributes.

Breaking Down the Solution

To resolve this, you'll need to go through the following steps:

1. Instantiate the Class

Before you can access the question or answer attributes, you need to create an instance (or object) of Class. Here's how you do that:

In this line, you create an instance of Class with your desired question and answer.

2. Accessing Instance Attributes

Once you have an instance, you can access its question and answer attributes like this:

Conclusion

By following this structure, you'll not only resolve the AttributeError, but also gain a stronger understanding of how to properly use classes in Python. Remember, to access instance attributes, you always need to create an object from the class. Happy coding!
