Python Coding Challenge - Question with Answer (ID -050526)

 

Explanation:

🔹 Step 1: Initialize the List

x = [1,2,3]

A list x is created

👉 Current value:

[1, 2, 3]

🔹 Step 2: Insert Element

x.insert(1,9)

insert(index, value) places the value at the given index

Elements at and after that index shift right

👉 Insert 9 at index 1

Before:

[1, 2, 3]

After:

[1, 9, 2, 3]

🔹 Step 3: Apply Slicing

x[1:3]

Slice from index 1 to 3 (3 is excluded)

👉 From [1, 9, 2, 3]:

Index 1 → 9

Index 2 → 2

👉 Result:

[9, 2]

🔹 Step 4: Print Output

print(x[1:3])

👉 Final Output:

[9, 2]
