Answer 2

for some reason it isnt working, when launched it just remains a blank screen

Answer 3

I just did it this morning. I'll take a look at it.

Answer 4

The only I see wrong right off the back is you never assigned in in your test statement to fix that you can add 1 argument to your test function which would be n. I'm going to try it now and tell you if it works.

Answer 5

You also didn't assign count in test(). I don't understand what you were trying to do with count in test I don't think those do anything

Answer 6

ok wait let me upload my most recent one

Answer 7

ok sorry some indentation issues...heres the most recent one, it just returns -5

Answer 8

ok still in test you are not giving it an argument therefore n is not assigned inside the function test(). Your argument should be test(n).

Answer 9

ok now it just returns -5 once...i guess thats an improvement

Answer 10

In your test function the body of your else statement should be even with "for a in range(0,n)" because the way yours is setup it will only check the first possible solution in stead of all solutions in (0,n) and would you rather me explain everything or post a fixed code.

Answer 11

can you please post a fixed code then if i have any questions ill ask you?

Answer 12

Yea one sec lemme do it really quick.

Answer 13

and i know some people use tuples or lists on this problem, thats not needed right?

Answer 14

No it can be done either way http://dpaste.com/hold/529001/

Answer 15

Do you want to see it done with a list?

Answer 16

no thanks, i havent tried it yet so i'd rather attempt on my own
but thanks for all the help!

Answer 17

so basically i just had to get rid of the else statement because it was causing it to check for only one value?

Answer 18

you had to add the argument to test which was test(n). I deleted the print n-5 in test there was no point to it. Your return n-5 should only be return n. I also deleted your n=0 its outside the function and isn't doing anything.

Answer 19

sorry I forgot to comment out the wrong stuff instead of deleting it.

Answer 20

its fine i understood it all, main thing was deleting the else statement...but why exactly do i need an arguement for test?

Answer 21

try it without the arguments you get a name error because functions have local variables. so unless you tell it to take an argument none of the variables you are already using will carry over. Therefor the n in cheese() will not moved to test() unless you tell it to by putting test(n).

Answer 22

Did that help?
