Python Coding challenge - Day 916| What is the output of the following Python Code?

 

Code Explanation:

1. Defining the Class

class Chain:

A new class named Chain is defined.

It will contain a method that supports method chaining.

2. Defining the step() Method

    def step(self):

        print("Step", end="")

        return self

Breakdown:

step() prints the word "Step"

end="" prevents a newline → printing happens continuously.

return self is the critical part:

It returns the same object

This allows calling another method on the same line.

In short:

Returning self allows multiple method calls one after another.

This is called method chaining.

3. Creating an Object

c = Chain()

An object c of class Chain is created.

4. Method Chaining in Action

c.step().step().step()

Step-by-step execution:

c.step()

prints: Step

returns c

(returned object).step()

again prints: Step

again returns c

(returned object).step()

prints final: Step

Each call prints "Step" and returns the same object again.

5. Final Output

All three prints combine into:

StepStepStep

Final Answer

Output:

StepStepStep
