贴了几个头，一共上路多少字节

同一份资料、同一种切法。这段程序输出一共贴了几个头和真正在线上跑的总字节数。它输出什么？

DATA, MSS = 1100, 400
PER = 20 + 20 + 14


def split(total, mss):
    out = []
    left = total
    while left > 0:
        take = mss if left > mss else left
        out.append(take)
        left -= take
    return out


pk = split(DATA, MSS)
print(str(len(pk) * 3) + "/" + str(DATA + len(pk) * PER))
