○ buddy
○ an error will occur

question 18

which of the following is not a valid attribute name in python?
○ my_attribute
○ _my_attribute
○ 123attribute
○ myattribute

Explanation:

Step1: Analyze first code snippet

The Dog class has an init method setting self.name to the input name. my_dog = Dog("Buddy") creates an instance with name="Buddy", then print(my_dog.name) outputs "Buddy".

Step2: Analyze second question

Python attribute names cannot start with a number. 123attribute starts with "123", so it's invalid.

Answer:

C. Buddy
C. 123attribute
