在Python中按索引从列表中删除元素的简便方法 [英] Concise way to remove elements from list by index in Python

问题描述

我有一个字符列表和索引列表

I have a list of characters and list of indexes

myList = ['a','b','c','d']
toRemove = [0,2]

我想一次完成操作

myList = ['b','d']

我可以这样做，但是有办法更快吗?

I could do this but is there is a way to do it faster?

toRemove.reverse()
for i in toRemove:
    myList.pop(i)

推荐答案

如果愿意，可以使用numpy.

import numpy as np

myList = ['a','b','c','d']
toRemove = [0,2]

new_list = np.delete(myList, toRemove)

结果:

>>> new_list
array(['b', 'd'], 
      dtype='|S1')

请注意，new_list是numpy array.
