List comprehensions-Wrong result - RavCOder - Oct-08-2019
Hi,
I don't understand why this code that I have write didn't work:
if __name__ == '__main__':
x = int(input())
y = int(input())
z = int(input())
n = int(input())
new_list =[ [a,b,c] for a in range (0,x +1) for b in range (0,y +1) for c in (0,z +1) if a+b+c != n]
print(new_list) Result :[[0, 0, 0], [0, 1, 0], [0, 1, 2], [1, 0, 0], [1, 0, 2], [1, 1, 2]]Correct result:
[[0, 0, 0], [0, 0, 1], [0, 1, 0], [1, 0, 0], [1, 1, 1]]Regards,
Ravcoder
RE: List comprehensions-Wrong result - buran - Oct-08-2019
what are the values of x, y, z and n when you run the code? And how you define the correct output? i.e. not example but in plain English
RE: List comprehensions-Wrong result - RavCOder - Oct-08-2019
the values of input are this:
1 1 1 2Instead for the output because I'm following an exercise that tells you what the correct output should be.

look at the part
for c in (0,z +1). You need it to be for c in range(0,z +1)As it is now c will take values of
0 and 2

My mistake I had not seen that I had not set range, thanks now it works !!!
