我有一个 python 列表说
a= ['Sample Date', '4/21/2015', '10/14/2014', '9/16/2014', '7/10/2014', '8/11/2014', '8/3/2014', '7/20/2014', '7/6/2014', '8/11/2014', '8/11/2014', '8/11/2014']
我有一个索引列表属于列表一个说
b=[5, 9, 10, 11].
获得以下输出的代码应该是什么
c= ['7/20/2014', '7/6/2014','7/20/2014', '7/6/2014']
最佳答案
使用简单的列表理解
>>> a= ['Sample Date', '4/21/2015', '10/14/2014', '9/16/2014', '7/10/2014', '8/11/2014', '8/3/2014', '7/20/2014', '7/6/2014', '8/11/2014', '8/11/2014', '8/11/2014']
>>> b=[5, 9, 10, 11]
>>> [a[i-1] for i in b]
['7/10/2014', '7/6/2014', '8/11/2014', '8/11/2014']
或者
>>> [a[i] for i in b]
['8/11/2014', '8/11/2014', '8/11/2014', '8/11/2014']
如果是从0索引开始
