阅读 一切从游戏开始

抄书：
def calc(seq):
 maximum = 0
 max_item = []

 for i in seq:
  product = (i[0]*100 + i[1]*10 + i[2]) * (i[3]*10 + i[4])
  if product > maximum:
    maximum = product
    max_item = i
  elif product == maximum:
    max_item += ','+i
    return max_item, maximum
  return max_item, maximum

seq = [ [5,6,7,8,9], [5,6,7,9,8] ]
max_item,maximum = calc(seq)
print "Maximum at", max_item, ",product", maximum


命令行下：C:\pylearn\first-step>python 1.py
Traceback (most recent call last):
  File "1.py", line 15, in ?
    max_item,maximum = calc(seq)
TypeError: unpack non-sequence

这是怎么回事情？！

  什么意思？？
在下没有试最初的脚本，仅仅是享受了一下子阅读，然后提取优化的代码段使用的，
