Python Coding Challange - Question with Answer (01220825)

 

 Let’s break this code step by step so it’s crystal clear.

---

🔹 Code:

s = 10
for i in range(1, 4):
    s -= i * 2
print(s)

---

🔍 Explanation:

1. Initialize:
   s = 10

2. Loop:
   The for loop runs with i taking values from 1, 2, 3 (because range(1, 4) stops before 4).

   • Iteration 1 (i = 1):
     s -= i * 2 → s = s - (1 * 2) → s = 10 - 2 = 8

   • Iteration 2 (i = 2):
     s = 8 - (2 * 2) → s = 8 - 4 = 4

   • Iteration 3 (i = 3):
     s = 4 - (3 * 2) → s = 4 - 6 = -2

3. After Loop Ends:
   s = -2

4. Print:
   Output → -2

✅ Final Output:

-2
