Python - Constructors and Object Initialization

Identify the error in this code:

class D:
    def __init__(self, val):
        self.val = val
    def show():
        print(self.val)

d = D(5)
d.show()

AIncorrect constructor syntax

BMissing <code>self</code> parameter in <code>show</code> method

CInstance variable <code>val</code> not defined

DCannot call method without arguments

Step-by-Step Solution

Solution:

Step 1: Check method definitions
All instance methods must have self as the first parameter.
Step 2: Identify missing self
The show method lacks self, so it cannot access instance variables.
Final Answer:
Missing self parameter in show method -> Option B
Quick Check:
Instance methods need self parameter [OK]

Quick Trick: Always include self in instance method parameters [OK]
