Python Coding challenge - Day 1081| What is the output of the following Python Code?

 

Code Explanation:

🔹 1️⃣ Defining Class A

class A:

    def f(self): return "A"

A base class named A is created.

It contains a method f().

When called, this method simply returns:

"A"

🔹 2️⃣ Defining Class B (inherits from A)

class B(A):

    def f(self): return super().f() + "B"

Class B inherits from A.

It overrides the method f().

Inside the method:

super().f() + "B"

Steps:

super().f() calls the parent class method (A.f()).

A.f() returns "A".

"B" is appended.

So:

B.f() → "AB"

🔹 3️⃣ Defining Class C (inherits from B)

class C(B):

    def f(self): return super().f() + "C"

Class C inherits from B.

It also overrides method f().

Inside the method:

super().f() + "C"

Steps:

super().f() calls B.f().

B.f() returns "AB".

"C" is appended.

So:

C.f() → "ABC"

🔹 4️⃣ Calling the Method

print(C().f())

Step-by-step execution:

Step 1

Create object of class C

C()

Step 2

Call method:

C.f()

Inside C.f():

super().f() + "C"

Step 3

Call B.f()

Inside B.f():

super().f() + "B"

Step 4

Call A.f()

return "A"

🔁 Return Flow

Now values return back step-by-step:

From A.f():

"A"

From B.f():

"A" + "B" = "AB"

From C.f():

"AB" + "C" = "ABC"

✅ Final Output

ABC
