Python Coding Challenge - Question with Answer (ID 140926)

 

Explanation:

1. Creating the List

a, *b, c = [2, 4, 6, 8, 10]

The list contains:

2, 4, 6, 8, 10

2. Star Unpacking

a, *b, c = [2, 4, 6, 8, 10]

Python assigns the values like this:

a gets the first value → 2

c gets the last value → 10

*b collects all the remaining values → [4, 6, 8]

So:

a = 2

b = [4, 6, 8]

c = 10

3. Calculating a * c

a * c

Substitute the values:

2 * 10 = 20

4. Calculating sum(b)

sum(b)

Since:

b = [4, 6, 8]

Therefore:

4 + 6 + 8 = 18

5. Final Calculation

a * c - sum(b)

Substitute:

20 - 18 = 2

6. print()

print(a * c - sum(b))

So the final output is:

Final Output:

2
