If you **execute** it, you will see the **same output** as before, but now something has happened. The two objects created have their own **sequence string** stored in the **strbases** attribute. Let's debug it to see it.

Each object has **its own sequence**! If you **debug** it using the **step into** option, you will see that the sequence is stored in the object when the **self.strbases = strbases** line is executed.
