问题描述
在Python中,我有一个元素列表 aList 和一个索引列表 myIndices 。有什么办法可以一次检索所有在 aList 中有 myIndices ?>>> aList = ['a','b','c','d','e','f','g']
>>> myIndices = [0,3,4]
>>> aList.A_FUNCTION(myIndices)
['a','d','e']
解决方案
我不知道有什么办法可以做到。但是您可以使用:
>>> [myList [i] for myIndices]
In Python I have a list of elements aList and a list of indices myIndices. Is there any way I can retrieve all at once those items in aList having as indices the values in myIndices?
Example:
>>> aList = ['a', 'b', 'c', 'd', 'e', 'f', 'g'] >>> myIndices = [0, 3, 4] >>> aList.A_FUNCTION(myIndices) ['a', 'd', 'e']
解决方案
I don't know any method to do it. But you could use a list comprehension:
>>> [aList[i] for i in myIndices]
