python子类分配

原问题是将左边样式变成右边样式：

即有父类和子类，父类包括多个子类，怎样将子类匹配到父类下面的问题

代码如下

 1 #!/usr/bin/python3.4
 2 # -*- coding: utf-8 -*-
 3 
 4 arr1 = ["S01","S01","S01","S02","S03","S04","S04"]
 5 arr2 = ["G0001","G0002","G0003","G0004","G0003","G0004","G0005"]
 6 # 用来存放父类
 7 father = []
 8 # 放入第一个单方便后面循环计算
 9 father.append(arr1[0])
10 # 子类
11 son = []
12 # 临时数组
13 temp = []
14 
15 for i in range(0,len(arr1)):
16     # 如果father里面存在，就跳过
17     # 把子类存入临时数组
18     if arr1[i] in father:
19         temp.append(arr2[i])
20         pass
21     # 如果father里面不存在
22     # 释放临时数组
23     else:
24         son.append(temp)
25         temp = []
26         father.append(arr1[i])
27         temp.append(arr2[i])
28 # 将最后一次循环的temp放入son
29 son.append(temp)
30 print(father)
31 print(son)

运行效果：
