列表解析 

 1 #!/usr/bin/env python
 2 l1 = ['x','y','z','w','e','r','t','v',]
 3 l2 = [1,3,4,5,2,6,7,]
 4 if len(l1) <= len(l2):
 5     for m in range(len(l1)):
 6         for i in l1:
 7             for j in l2:
 8                 if l1[m] == i and l2[m] == j:
 9                     print((i,j))
10 else:

12         for i in l1:
