Question

Python字典如何通过一部分字找到含有这些字所有的value

{'box1': {'apple', 'orange', 'football', 'baseball'}, 'box2': { 'basketball', 'cherry', 'blueberry'}
期望输出是
box1 has these balls:
football
baseball
box2 has these liver samples:
basketball
谢谢！

Answer 1

1. 首先，你的数据结构定义错了，没有这种结果。只有{‘box1':[xx,xx,xx]}
   

2. for key,vals in 你的字典对象：

   print '%s has these balls ' %key

   for val in vals:

   if val.find('ball') >= 0:

   print val
   

Answer 2

用find方法找到有ball的字符，打印出来就行了
