Question

What is the output?

answer = 0

for numA in [2,4]:

for numB in [3, 5]:

answer = answer + numA + numB

print (answer)

Output:

Answer 1

Answer:

The output is 28

Explanation:

Required

Determine the output of the code segment

The first line initializes "answer" to 0

The next two lines iterate through lists [2,4] and [3,5

Each of these lists have two elements; So, the number of iterations is 2 * 2 i.e. 4.

In the first iteration

numA = 2, numB = 3, answer = 0

So:

$answer = answer + numA + numB= 0 + 2 + 3 = 5$

In the second iteration

numA = 2, numB = 5, answer = 5

So:

$answer = answer + numA + numB= 5 + 2 + 5 = 12$

In the third iteration

numA = 4, numB = 3, answer = 12

So:

$answer = answer + numA + numB= 12 + 4 + 3 = 19$

In the fourth iteration

numA = 4, numB = 5, answer = 19

So:

$answer = answer + numA + numB= 19 + 4 + 5 = 28$

Lastly, the value of "answer" is printed

Hence, the output is 28
