Answer 1

Be careful with how you tab your answer. The code you made should give you the correct answer so long as the shell can actually read your code.

format your answer like this:

sum = 0

for i in range(0, 101):

(tab) if i%2 == 0:

     (tab) sum = sum + i

Be sure that the answer is tabulated properly (either press tab or press space 4 times in the areas where I placed tab in parenthesis).

Additionally you can answer the question more efficiently like this:

sum = 0

for i in range(0,101,2):

sum += i

The bold 2 represents the steps you want the iteration to take. In this case, because the step is 2, the loop increases by 2 with each pass. Using this method i will automatically be all even numbers.

sum += i essentially translates to sum = sum + i

it is just a shorter way of expressing it.

Hope this helps.
