[Solved] Identify the problem in this code:class Tree: height = 10 t = Tree() print(t.height) Tree.height = 15 print(t.height) | Python

Python - Classes and Object Lifecycle

Identify the problem in this code:

class Tree:
    height = 10

t = Tree()
print(t.height)
Tree.height = 15
print(t.height)

AOutput will be 10 then 10, class attribute change ignored

BError because instance attribute height is missing

CError because class attribute cannot be changed

DOutput will be 10 then 15, no problem

Step-by-Step Solution

Solution:

Step 1: Understand attribute access
Initially, t.height accesses class attribute 10.
Step 2: Class attribute update effect
Changing Tree.height to 15 updates class attribute; t.height reflects this change.
Final Answer:
Output will be 10 then 15, no problem -> Option D
Quick Check:
Class attribute changes reflect in instances without instance override [OK]

Quick Trick: Instance uses updated class attribute if no instance attribute exists [OK]
