Common Mistakes

Returning self.id instead of self.name

Returning self without converting to string

Using a method name other than __str__

The __str__ method should return a string that represents the object. Returning self.name shows the product's name.

💡 Hint

Common Mistakes

Using variable names without self

Swapping first_name and last_name

Inside the f-string, you need to use self.first_name for BLANK_1 and self.last_name for BLANK_2 to access the instance's attributes and form the full name.
