    different_sum6 = 0

for p in range(1,6+1):
    for q in range(1,6+1):
        if (p+q) == 6 and (p != q):

print(str((different_sum6//different_sum6))+"/"+str((total_rolls//different_sum6)))

    Python3:

    import fractions

if __name__ == "__main__":
  count_all, count_sum6 = 0, 0
  for i in range(1,6+1):
    for j in range(1,6+1):
      count_all += 1
      if i != j and i + j == 6:
         count_sum6 += 1
        
  print(fractions.Fraction(count_sum6, count_all))

    Python code

    from fractions import Fraction

count = 0

def func(count):
    for i in range(1, 7, 1):
        for j in range(1, 7, 1):
            if (i != j) and (i + j) == 6:
                count += 1
    
    return Fraction(count, 6*6)


print(func(count))

    The instructions kind of cheat. It says "put your answer in the editor" below. There is no editor "below" (there's on to the side). So I figured they must have meant the "custom input", since the program refused to accept an aswer when I tried doing a printf. But when I put an input into the custom input, it said I was wrong (I didn't see that you can't use 3/3 and 3/3 as valid outcomes). So I picked the correct answer, and still got an error. Finally decided to use both a custom input and a printf... and now it works.

    So put your answer in the custom input and a printf.

    Python 3

    dice=[1,2,3,4,5,6]
comb=[(a,b) for a in dice for b in dice]       
favourable=[(a+b)==6 for a,b in comb if a!=b]       

sum(favourable)/len(comb)
