@@jaubee Dude I'm pretty sure the answer is 2318. You put 2 if statements I think that's why you got a different answer. It's adding the total from the first if statement to the next one, instead of adding all of them at once. Use an "or" like the comment above and you will get 2318.

Great video. All the explanations are very clear. These are my attempts. With "Compute" I wasn't if you mean to just show all the multilpes of 3 and 5 or also sum them, so I have tried both. To show all the multiples of 3 and 5: for i in range(1, 100): if i % 3 == 0 or i % 5 == 0: print(i) To sum them: total4 = 0 for i in range(1, 100): if i % 3 == 0 or i % 5 == 0: total4 += i print(total4) Total is 2318

[@mingji753]

if we only have to find the sum of multiples of 3 the formula is: for i in range(1, 101): if i % 3 == 0: print(i) #To add them total = 0 for i in range(1, 101): if i % 3 == 0: total = total + i print(total) the answer is 1683

[@TheProGam3rHD]

I can't believe I figured this on my own! For the multiple of 3, alternatively, you can use a nested for loop: for i in range(1, 8): for n in range(1, 8): if i / 3 == n: total3 += i print(total3) Although inconvenient, this circumvents the need to use the modulo operator. This is what I came up with because I didn't even think to use it.

your code is incomplete. You have to reduce those numbers which are common multiple of 3 & 5, for eg, 15,30... these numbers would have come twice with the above code.

[@ivanott7196]

When I studied programming at university, I thought I was stupid for being very slow to understand it. As a geo-engineer, we basically understand something through why the result or outcomes become like that instead of just accepting it has to be like that. The programming teacher basically just asked us to watch videos, take tests and do little projects but barely teaching in the depth. I was kinda angry because I think she needs to use different methods how to teach programming to the future engineers, instead of treating us like future IT guys. So this channel does make me understand in detail why the outcomes like that. Thank you!

fantastic, I loved the fact that you gave a little challenge at the end of the video it makes learning so much fun! btw, here's the code: total = 0 for i in range (1, 100): if (i % 3 == 0) or (i % 5 == 0): total += i print(total) output = 2318

[@ev_dash]

let me try running your work. what I did initially was: total4 = 0 for i in range(1, 100): if (i % 3 == 0, i % 5 == 0): total4 += i print(total4) 4950 let me know if I made any errors.

[@akhilaugustine2858]

total=0 a= list(range(1,100)) for x in a: if x %3==0 or x%5==0: total+=x print (total) >>>2318

[@todaystop3768]

But why can't we write x % 3 or x % 5 == 0: BTW it gives a wrong answer

[@yyaaas6691]

no need to make a list and put it in a for the for loop

Wow, some of you people are really smart. My answer did not even come close and some of you had nice, simple solutions.

[@trianglebean3884]

don’t sell yourself short b! everyone in the comments are at different levels, and people only post those when they’re pretty confident about it. keep going n you’ll be spitting out nice, simple solutions too !!!

[@deVon30241]

@@trianglebean3884 much appreciated. Coding is so open ended in a way, which kinda throws me off, it requires a different kind of thinking than I'm used to. There's many ways to reach a solution, but there's always a best way, that requires some creativity and a fundamental understanding of the program. Its fun!

total4 = 0 for f in range(1,100): if f % [3,5] == 0: total4+= f print(total4) The Answer will be 1683 950 respectively.

Very clear explanation, thank you. Here is my code: total = 0 for i in range(1, 100): if (i % 3 or i % 5) == 0: total += i print(total)

[@peethos]

If I'm not mistaken, you're not supposed to use brackets in the third line, you're supposed to separate the two arguments so the code should look something like this total = 0 for i in range(1, 100): if i % 3 ==0 or i % 5 ==0: total += i print (total) And on the terminal you should get 2318. I hope it helps.

[@carloscosta2751]

@eman elkholy That's odd. Make sure you have declared an empty list before the loop typing list_name = [ ]. When you don't declare a list making it equal to an empty pair of square brackets, Python considers it as an integer. That's probably where your error comes from.

[@MinhBinh-dr9rc]

Its not correct. Dojo said "the both multiple of 3 and 5...and 15 is the first number". So I think it have to be: if (e%3==0) and (e%5==0):

[@Zilgamech]

​@@MinhBinh-dr9rc He explains @9:35 that you sum 3, 6 then 9 and so on... And noticed that eventually you get to 15 which is a multiple of both. That's why your code is wrong because it only counts the numbers that are multiples of 3 and 5 instead of the multiple of 3 and the multiples of 5 like he explains.
