Python Coding Challenge - Question with Answer (ID 300826)

 

Explanation:

1. Create the Range

x = range(10, 0, -3)

Here, range() takes three arguments:

range(start, stop, step)

So:

Start = 10

Stop = 0

Step = -3

2. Understand the Negative Step

Because the step is -3, Python moves backward by 3 each time.

Starting from 10:

10 → 7 → 4 → 1

Python stops before reaching 0.

So x effectively contains:

10, 7, 4, 1

3. sum(x)

sum(x)

The sum() function adds all values in the range:

10 + 7 + 4 + 1

Calculate:

10 + 7 = 17

17 + 4 = 21

21 + 1 = 22

Therefore:

sum(x) = 22

4. print() Displays the Result

print(sum(x))

Python prints:

✅ Final Output

22
