Python Coding Challange - Question with Answer (01200925)

 

Let’s break it step by step 👇

a = [0] * 4

• [0] is a list with a single element → [0].

• * 4 repeats it 4 times.

• So, a = [0, 0, 0, 0].

---

a[2] = 7

• In Python, list indexing starts at 0.

• a[0] → 0, a[1] → 0, a[2] → 0, a[3] → 0.

• The code sets the 3rd element (index 2) to 7.

• Now a = [0, 0, 7, 0].

---

print(a)

• This prints the final list:

[0, 0, 7, 0]

✅ Output: [0, 0, 7, 0]
