Solution

The output of these lines will be 89.

Here's the step-by-step explanation:

  1. A class User is defined with a class attribute id set to 1.
  2. An instance u of the class User is created.
  3. The id attribute of the instance u is set to 89.
  4. The class attribute id of the User class is set to 98.
  5. print(u.id) is called. Since the instance u has its own id attribute, the value 89 is printed. The class attribute id is not accessed in this case because the instance u has its own id attribute.
