Problem in Python Challenge

Question

Hi, the question was "What's the output of the following code?"

dict = {1:15, 5:10, 4:26}
sum = 0
for value in dict:
sum = sum + value
print(sum)

Correct Answer: 10

I thought the correct answer would be 51, can anyone explain why 10 is correct?
Thanks!

Answer 1

When you loop in a dict, you're looping in the keys, so sum would be 1+5+4=10
EDIT:
If you want to loop key values, then use sum = sum + dict[value]
