zip 中数组加 * 号， 为解压的意思
```
In [123]: list(zip([1,2,3,4]))
Out[123]: [(1,), (2,), (3,), (4,)]

In [124]: a=[1,2,3]
     ...: b=[4,5,6]
     ...: c=[7,8,9]
     ...: list(zip(a,b,c))
     ...:
Out[124]: [(1, 4, 7), (2, 5, 8), (3, 6, 9)]

In [125]: ret = list(zip(a,b,c))

In [126]: ret
Out[126]: [(1, 4, 7), (2, 5, 8), (3, 6, 9)]

In [127]: list(zip(*ret))
Out[127]: [(1, 2, 3), (4, 5, 6), (7, 8, 9)]

In [128]: a=[1,2,3]
     ...: b=[4,5,6,7]
     ...: c=[8,9,10,11,12]
     ...:

In [129]: list(zip(a,b,c))
Out[129]: [(1, 4, 8), (2, 5, 9), (3, 6, 10)]
