What will be the output of this code?

class Counter:
    count = 0
    def __init__(self):
        Counter.count += 1

c1 = Counter()
c2 = Counter()
print(Counter.count)

A0

B2

CError

D1

Step-by-Step Solution

Solution:

Step 1: Understand class variable behavior
The variable count is a class variable shared by all instances. Each time an object is created, Counter.count increases by 1.
Step 2: Count the number of objects created
Two objects c1 and c2 are created, so Counter.count becomes 2.
Final Answer:
2 -> Option B
Quick Check:
Class variable increments = 2 [OK]

Quick Trick: Class variables shared across all instances [OK]
