Solution

The output of these lines will be 98.

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. This does not affect the class attribute id.

  4. The class attribute id is set to 98. This does not affect the id attribute of the instance u.

  5. print(User.id) prints the current value of the class attribute id, which is 98.
