Python Coding Challenge - Question with Answer (01161125)

 Explanation:

List Initialization

a = [1, 4, 7, 10]

You create a list a that contains four numbers:

1, 4, 7, 10

Variable Initialization

s = 0

You create a variable s to store the sum.

Initially, sum = 0.

Loop Through Each Value

for v in a:

This loop will pick each value from list a, one by one.

So v becomes:

1 → 4 → 7 → 10

Check Condition

if v % 3 == 1:

You check if the number leaves remainder 1 when divided by 3.

Let’s check each:

v v % 3 Remainder Condition v%3==1?

1 1             Yes             ✔ Add

4 1             Yes             ✔ Add

7 1             Yes             ✔ Add

10 1             Yes             ✔ Add

All numbers satisfy the condition.

Add to Sum

s += v

Add all numbers that passed the condition.

s = 1 + 4 + 7 + 10 = 22

Print the Final Sum

print(s)

This prints:

22

Final Output: 22
