Question
What do these lines print?class User: id = 1u = User()print(u.id)
Solution 1
The code defines a class User with a class attribute id set to 1. Then it creates an instance u of the class User. When print(u.id) is called, it prints the value of the attribute id of the instance u. Since id is a class attribute and we haven't defined an instance attribute with the same name, it refers to the class attribute. Therefore, the output of this code will be 1.
Solution 2
The code defines a class User with a class attribute id set to 1. Then it creates an instance of the class User and assigns it to the variable u. When print(u.id) is called, it prints the id attribute of the User instance u.
So, the output of this code will be 1.
