Python coding challenge - Day 3 | Output Prediction MCQ

 What Is the Output of This Python Code?

 Question :  

x = [10, 20, 30]

x.insert(1, 15)

print(x)

Options :

A) [10, 15, 20, 30]

B) [15, 10, 20, 30]

C) [10, 20, 15, 30]

D) Error

 

Correct Answer :

A) [10, 15, 20, 30]




Explanation :

first we create a list :

x = [10, 20, 30]

The list contains three elements.




Index : 0   1   2

Value :10  20  30

step 1 - insert ( )

x.insert(1, 15)

insert (index , value ) adds an element at a specific position in the list.

Here :

1 → position where the value will be inserted

15 → value to insert

So 15 is inserted at index 1.

The list becomes :

[10, 15, 20, 30]

Step 2 - print ( )

print(x)

Output :

[10, 15, 20, 30]
