Python Coding challenge - Day 915| What is the output of the following Python Code?

 Code Explanation:

1. Defining the Class

class Numbers:

This line creates a new class named Numbers

The class will behave like an iterable object

2. Defining the __iter__ Method

    def __iter__(self):

        return iter([1, 2, 3])

What this means:

__iter__() is a special method used by Python to make objects iterable.

When a loop asks for an iterator, Python calls this method.

iter([1, 2, 3]) creates an iterator over a list [1, 2, 3]

So the class returns an iterator that yields 1, then 2, then 3

In short:

This class makes itself iterable by returning an iterator of a list.

3. Creating an Object

obj = Numbers()

An object obj of class Numbers is created.

It is now an iterable object because it defines __iter__().

4. Using a for Loop to Iterate

for i in obj:

What happens internally:

Python calls obj.__iter__()

This returns an iterator for [1, 2, 3]

The loop then takes each value one by one:

1 → 2 → 3

5. Printing Each Item

    print(i, end="")

Each item (i) is printed without spaces or newline

end="" means:

print items continuously with no extra spaces

6. Final Output

The loop prints:

123

Because:

Items 1, 2, and 3 print right next to each other.

Final Result

Output:

123

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
