从python中的列表中删除单词 [英] Removing words from list in python

问题描述

我有一个列表"abc"(字符串)，我试图从列表"abc"中删除列表"stop"中存在的某些单词以及abc中存在的所有数字.

I have a list 'abc' (strings) and I am trying to remove some words present in list 'stop' from the list 'abc' and all the digits present in abc.

abc=[ 'issues in performance 421',
 'how are you doing',
 'hey my name is abc, 143 what is your name',
 'attention pleased',
 'compliance installed 234']
stop=['attention', 'installed']

我正在使用列表推导将其删除，但是下面的这段代码无法删除该单词.

I am using list comprehension to remove it but this below code is not able to remove that word.

new_word=[word for word in abc if word not in stop ]

结果:(注意词仍然存在.)

Result:(attention word is still present.)

['issues in performance',
 'how are you doing',
 'hey my name is abc, what is your name',
 'attention pleased',
 'compliance installed']

所需的输出:

 ['issues in performance',
     'how are you doing',
     'hey my name is abc, what is your name',
     'pleased',
     'compliance']

谢谢

推荐答案

这是一个解决方案，它使用带有 re.sub 方法的简单正则表达式.此解决方案还删除了数字.

Here is a solution, using simple regular expression with the re.sub method. This solution removes numbers as well.

import re

abc=[ 'issues in performance 421',
 'how are you doing',
 'hey my name is abc, 143 what is your name',
 'attention pleased',
 'compliance installed 234']
stop=['attention\s+', 'installed\s+', '[0-9]']

[(lambda x: re.sub(r'|'.join(stop), '', x))(x) for x in abc]


'Output':
['issues in performance ',
'how are you doing',
 'hey my name is abc,  what is your name',
 'pleased',
 'compliance ']
