What will be the output of this code?

class Cat:
    def __init__(self):
        self.sound = 'meow'

c = Cat()
print(c.sound)
c.sound = 'purr'

AError at assignment

Bmeow purr

Cpurr purr

Dmeow meow

Step-by-Step Solution

Solution:

Step 1: Understand initial attribute value
The constructor sets self.sound to 'meow', so c.sound initially prints 'meow'.
Step 2: Attribute modification
After assignment c.sound = 'purr', the attribute value changes, so printing again outputs 'purr'.
Final Answer:
meow purr -> Option B
Quick Check:
Attribute change reflected in output = meow purr [OK]

Quick Trick: Changing attribute updates its value immediately [OK]
