Python Coding Challange - Question with Answer (01050925)

 

Step 1️⃣ Original List

a = [1, 2, 3, 4]

Index positions:

• a[0] → 1

• a[1] → 2

• a[2] → 3

• a[3] → 4

---

Step 2️⃣ Slice Selection

a[1:3] selects the elements at index 1 and 2 → [2, 3].

So we’re targeting this part:

[1, (2,3), 4]

---

Step 3️⃣ Slice Replacement

We assign [9] to that slice:

a[1:3] = [9]

So [2, 3] is replaced by [9].

---

Step 4️⃣ Final List

a = [1, 9, 4]

---

✅ Output:

[1, 9, 4]
