WebOutput: 15. However: print (min (x for x in range (1,300) if x % 2 != 0 if x % 2 != 1)) Output: ValueError: min () arg is an empty sequence. There are no integers that are both odd and even, so there are no values for min to see, so it throws an exception. I deduce that in your code, there are no values that pass both conditions.
