Total3times = 0

for i in a:
    if i%3 == 0 :
        Total3times += i
        i += 1
        print(i,Total3times,Total5times)
        break
    elif i%5 == 0 :
        Total5times += i
        i += 1
        print(i,Total3times,Total5times)
        break
    else :
        i += 1
        break

你想达到什么样的效果执行不出来?

所有的i += 1 都是画蛇添足  应予以删除

最后一行删除。
