y[15] (因为15是 x[14]

y 只有15个元素,并且由于列表项从索引0开始,因此 list index out of range .

zip 跳过 None

x = [1,2,3,4,5,6,7,8,9,10,11,12,13,14,15]

y = [None,None,None,None,None,10,20,30,40,50,60,70,80,90,100]

result = []

for val_x, val_y in zip(x, y):
    if(val_y is None):
        continue
    result.append(val_x - val_y)

print(result)

输出:

[-4, -13, -22, -31, -40, -49, -58, -67, -76, -85]

或者作为列表理解:

result = [ (val_x - val_y) for val_x, val_y in zip(x, y) if (val_y is not None) ]
