Question
What do these lines print?class User: id = 1u = User()u.id = 89User.id = 98print(u.id)None18998
Solution
The output of these lines will be 89.
Here's the step-by-step explanation:
- A class
Useris defined with a class attributeidset to1. - An instance
uof the classUseris created. - The
idattribute of the instanceuis set to89. - The class attribute
idof theUserclass is set to98. print(u.id)is called. Since the instanceuhas its ownidattribute, the value89is printed. The class attributeidis not accessed in this case because the instanceuhas its ownidattribute.
