Python - Inheritance and Code Reuse

What will be the output of this code?

class A:
    def show(self):
        print('A show')

class B(A):
    def show(self):
        print('B show')
        super().show()

b = B()
b.show()

AA show B show

BB show A show

CB show

DError: super() call invalid

Step-by-Step Solution

Solution:

Step 1: Trace the method calls in B.show()
First it prints 'B show', then calls super().show() which prints 'A show'.
Step 2: Determine output order
Output is 'B show' first, then 'A show' on next line.
Final Answer:
B show A show -> Option B
Quick Check:
Child prints then super() parent prints = D [OK]

Quick Trick: super() calls parent after child's code if placed after print [OK]

Common Mistakes:

Assuming parent prints first
Expecting error from super()
Confusing print order
