index 是来表示你的数组位置的，你需要一个一个来判断奇偶，所以需要判断每一个位置的，index从0开始，意味着从第一个数开始判断。这是我的code：def sub_sum(l): n = 0 odd = [] even = [] for num in l: if n % 2 == 0: odd.append(num) else: even.append(num) n += 1; sumo...

布尔值是逻辑判断时用的and：且的关系，a and b，及a和b的都为真时，才为真or：或的关系，a or b，只要有一个为真就返回真，都假才为假not：相当于取反， not a，若a为真，则 not a就是假，反之亦然
